Data Collection or Procedure Questions
1. What species should I study for BFL?
You first need to find out which species breed in your state or province and then figure out what type of habitat these species like to use for breeding. Check the Which Species Can I Study? table and then look at the individual species accounts for detailed range maps and habitat preferences of your selected species.

Go back

2. If the species I wish to study is listed in a different region on the CD and species list, can I still survey for this bird or should I only study the birds listed in my region?
You can study any species in any region as long as it has the potential of breeding within the habitat that you have selected. Species that breed in multiple regions were listed in the region where we have the least amount of data for these birds.

Go back

3. When should I begin my surveys for BFL?
Visit 1 should take place on the earliest date that all of your study species are present and expected to be breeding. Determine your first visit date by consulting the summary table of breeding chronology under Survey Instructions.

Go back

4. When should I complete Visit 2?
Visit 2 should occur approximately two to four weeks after Visit 1, when you have the maximum chance of confirming breeding activity for all your study species.

Go back

5. Can I use contiguous forest patches or do all my study sites have to be in isolated patches of forest?
We need data from all forest types so feel free to select sites in very small patches of forest to large contiguous stands.

Go back

6. How many Field Forms do I use per study site?
You should use 2 Field Forms per study site. Fill out the front of the form for each visit. You only need to fill out the back of the form once, so one back will be blank.

Go back

7. If I am using the same study sites that I used for BFL in the past do I need to fill out the Habitat Characteristics portion of the Field Form again?
If you are using the same sites, you do not need to fill out the backside of the Field Form and Habitat Characteristics on the web unless one of these variables has changed at your site. If something has changed, on the back of your Field Form please only fill in the field(s) that have changed. On the web under the “Add Site” button, copy your BFL survey point from a previous season and make the appropriate change under the “Describe Habitat Characteristics” button, then save your data.

Go back

8. If I do not see or hear my study species do I still need to fill out a data form for this species?
Even if you do not detect one or all of your study species, please still fill out a data form. Negative data, or no detection of a species, is just as important as finding the bird since we need to know where these birds are breeding as well as where they are not breeding.

Go back

9. What do I do if I detect the target species before or after I do the official protocol, but I don't detect it during the actual survey periods?
You should mark "not seen or heard" for each of the three survey periods (O, P, and B), and then make notes about your detection of the target species in the comments section.

Go back

10. Am I still required to make additional visits to my study sites to search for nests after I have finished Visit 1 and Visit 2?
No. We added a 10-minute Behavior Watch Period to the protocol to provide a low impact method of determining your study species’ breeding status. This consists of a 5-minute mobbing call sequence that you will play in the field and then a 5-minute look and listen period. We expect this protocol to be less invasive than nest searching and less time consuming for you, the participant.

Go back

11. Do I need to fill out all the habitat variables on the back side of the Field Form and the web data form?
Yes, please try and fill in all the fields on the backside of your Field Form to the best of your ability. Good estimates are better than leaving boxes blank since we can not analyze your data without all the variables. If you need help, please contact your local site coordinator or contact the BFL staff for help.

Go back

12. What number do I record for Forest Patch Size if my forest patch is contiguous across a large landmass such as an entire state?
Try to come up with your best estimate, if it exceeds the number of characters that we allow then enter 999,999 and record the number in the comments section.

Go back

13. If I fill out the web data form, do I still need to send in copies of my Field Forms?
Yes, please still send in photocopies of your Field Forms in case we have questions related to your data.

14. Where can I find maps for BFL?
See the information about map resources.

Go back

15. How do I enter the latitude and longitude of my study site?
U.S. participants can link to the online topographic map at "topozone.com" to help find their lat/long. (Helpful hint: you will later be asked to provide the elevation of your study site. Try to obtain your elevation from the online topographic map while you're there.) Unfortunately, at this time we don't have a similar map web site for Canada.

PRIVACY STATEMENT: Please note that if you enter the latitude and longitude of your study site, the precise location of your study site will appear on maps when people retrieve bird data from our site. Your name and personal information will NOT appear, however, unless the "unique site name" that you chose for this site includes that information.

16. What are "Decimal Degrees"?
Decimal Degrees (DD) are an alternate way to express the more familiar Degrees-minutes-seconds (DMS) measurements of latitude and longitude. We require all latitude and longitude measurements in DD because our computer programs cannot work with the DMS format.

Go back

17. How do I convert Degrees-Minutes-Seconds" to "Decimal Degrees"?
To convert Latitude/Longitude coordinates from Degrees-Minutes-Seconds(DMS) to Decimal Degrees (DD) use one of the following:

  • Use an on-line Degrees to Decimal Degrees Converter; use your browser's back button to return to this page
  • Convert DMS to DD by hand, using this formula:

    degrees + (minutes/60) + (seconds/3600)

    For example, if you calculated your latitude in DMS as 46º 20' 10" the DD equivilent would be:

    46 + (20/60) + (10/3600) = 46 + (.33333) + (.00278) =   46.33611

  • We suggest rounding to the 5th decimal place.
  • Don't forget that longitudes in North America are negative!

On-line Data Entry Questions
1. How do I log into the Data Entry Section?
Please review the step-by-step instructions for logging into the Data Entry section of our web site. Access is restricted to people signed up to participate in BFL in the current year.  Please e-mail us at forest_birds@cornell.edu if you are interested in participating or have not renewed this season.

Go back

2. What does "Remember my password" mean?
If you select this option, you won't have to remember your password the next time you enter the data entry site. In fact, you won't even see the Log-in box at all. This is true, however, only if you do NOT log out between sessions.

If you choose to log out after a session, you will be prompted for your password the next time you enter the site, even if you clicked on 'Remember my password' before exiting your browser.

Go back

3. What is my Login Name and password?
As explained in the step-by-step instructions for logging into the Data Entry section, you select your own Login Name and password when you create your citizen-science online profile.

  • If you remember your Login Name but not your password, use the "click here for an e-mail reminder" link on the Login Box.  Your password will be sent to you automatically
  • If you created a Login Name and password in the past, but do not remember what they are, please contact us at forest_birds@cornell.edu.   Due to a small staff, please note that it may take a few days to receive your Login Name and password when contacting forest_birds@cornell.edu

Go back

4. Where do I find my “Login ID Number”?
Your ID number can be found just above your name on the mailing label of the Research Kit you received in the mail.  If you do not have this item anymore and have no idea what your ID number is, contact us at forest_birds@cornell.edu and we can send you your ID number.

Go back

5. When logging in I receive a message that an “identity certificate has expired.” How do I fix it?
This is a browser problem that is fixed by upgrading to a newer version of your web browser. We recommend using Internet Explorer version 4.0 or higher, or Netscape Navigator version 4.0 or higher.

If you use a PC and would like to update your version of Internet Explorer, click here.

If you use a Macintosh and would like to update your version of Internet Explorer, click here.

For either PCs or Macintosh, if you would like to update your version of Netscape, click here.

6. HELP! I can’t log in. When I click on Data Entry, I get an error that says, “We were not able to confirm your registration code(s). Please return to the previous page and try again.” What do I do?
This happens if you have inadvertently tried to create more than one online profile. Many users have successfully created online profiles and entered their ID number once, but for some reason were not aware that they did so. So, they returned to the Login box, clicked on Create an online profile, and entered their Login Name. When they put in the same Login Name that they used before, the database told them that someone is already using it (THEY are, under their first Login Name) and to enter a new, different Login Name.

Because this is a new Login Name, it needs a valid BFL ID to access the site. But because their ID was already acknowledged by their prior, successful login, the user becomes stuck.

Furthermore, their computer "remembers" this NEW Login Name when they come back to login, so they are immediately sent right to the "Project Sign-In" page and are asked to enter their BFL ID.

To fix the problem, you must erase any 'memory' your computer has of your newest Login Name and enter your FIRST original, successful Login Name. To do this:

  1. Close your browser and open it again, go to BFL’s home page (http://www.birds.cornell.edu/bfl) and click on the Data Entry button.
  2. Click "Click here to Log In.”  This should call up the Login Box.
  3. Enter your FIRST Login Name and password. If you don't remember your password, click on "Forgot your password? Click here for an e-mail reminder." Be sure to enter the Login Name that you ORIGINALLY selected.
  4. If you don't see the Login Box when you click on Data Entry (after exiting your browser), but are sent immediately to the Project Sign-in page that requests your ID, carefully read it. Look for the line that says: "If you have seen this page before, then you probably have inadvertently created a second profile. If this was not your intention, click here." This should present you with the Log-In box. If it doesn't, then you must "delete your cookies." See the next FAQ (#6, below) to learn how.

7. How do I "delete cookies" on my computer?
Search your computer's hard drive (usually the c:/ drive) for your cookies file and delete it.

On PCs, go to the Start Menu and click the "Find" menu option.

  • Find "Files or Folders" and when the window pops up, enter "cookies.txt" in the 'Named' box. Make sure the second box, called 'Look in,' has the correct hard drive directory (usually the c:/ drive) listed.
  • Click "Find Now" to find the file. Delete it.

On Macintosh, you can find your cookies file by going to the Apple file menu and scrolling down to "Find File."

  • Enter "cookies" in the blank "name contains" box.
  • Click "Find" to find the file. Delete it.
  • If you run Netscape on your Mac, please contact us instead.

Return to Data Entry and log in using the appropriate Login Name and password.

Go back

8. What if I can't remember my password?
If you don't remember your password, click on "Forgot your password? Click here for an e-mail reminder" in the Login Box. Be sure to enter the Login Name that you ORIGINALLY selected. If you still experience problems, send an e-mail to forest_birds@cornell.edu.

Go back

9. Should I log out of the database?
You don't have to log out of our server, but in doing so, it will prevent anyone else who might use your computer from accessing the server in your name.

You can log out of the server by clicking "Log out of database" under the Options/HELP menu tab or,  unless you check "Remember my password," by exiting your browser (by pressing "exit" of your browser's file menu).  Please note that if you choose to log out after a session, this will automatically clear the 'Remember my password' box and you will be prompted for your password on your next visit to the site.

Go back

10. I see an "Error on Page" or a "JavaScript Error" on my screen. What do I do about it?
If this happens to you, please call up a Java-console message on your computer and send it to us. To do this:

  • On Netscape browsers, type JavaScript: (include the colon) into the web address line. For example, if you were on a web page address such as http://www.birds.cornell.edu/bfl/bfl_data_entry.html, please highlight that whole address, then type JavaScript: over the existing address and press 'Go' or 'Enter.' Doing so will call up a Java-console message window.
  • On Internet Explorer, select 'View' from the main browser menu, then select 'Java Console.' Doing so will call up a Java-console message window.
  • Please copy the Java-console message that you see into an e-mail and send it to efb13@cornell.edu. Include a description of what you were doing at the time you saw the error message and the version number of your web browser. We'll try to figure out the problem for you.

11. I see an error message "SQL call failed [Oracle][ODBC] Syntax error or access violation" on my screen. What does this mean?
This error message has been reported by a handful of participants who run Netscape 4.5 or 4.7 on their computers, and indicates that your browser is having difficulty communicating with our server. The majority of Netscape 4.5 and 4.7 users don't report this problem, so it seems to be something unique about your computer set-up. We're looking into what that might be. In the short term, your best bet is to change your web browser to Microsoft Internet Explorer. This is not a product endorsement, only a practical consideration.

Go back

12. What does it mean to "Copy my sites from a previous season?"
This is relevant only for returning BFL participants who have submitted data to us in the past. If your previous season's data were successfully submitted, each study site was tagged with your BFL ID number.  When you log in and enter your authorization code (ID number),  our database will automatically retrieve the information associated with that ID number.

Go back

13. Why can't I find my previous BFL study sites on the check-in list?
There may be a few reasons why your previous data were not recalled:

  • Our office did not receive your data for this site.
  • You did not complete both site visits.
  • You did not include all the habitat characteristic variables (site data) about your study sites.
  • Your BFL ID number has changed since you last submitted data.
  • Your forms were submitted late and have not been processed yet.

If you submitted site data for a previous year and they are not available to be recalled, contact Jim Lowe at  (607) 254-2413 or jdl6@cornell.edu

Go back

14. Why use the new mapping tool to locate my study sites?
This is the most precise way of determining the lat/long of your study site, but it requires you to have a newer browser (view browser requirements). The mapping program will allow you to zoom into the location of your study site on a topographic map or aerial photograph by selecting your state or Delorme Atlas page. Step-by-step instructions are provided that will enable you to mark the precise location of your survey point and have the lat/long automatically downloaded into the project database. Step-by-step instructions are provided as links within the mapping tool.

Go back

15. How do I change the lat/long for a survey site that already has information in the database?
Presently, the only way to change lat/long for any survey site is to delete that site and re-enter the data under a new name. In the future it will be possible to change lat/longs directly, but for now you must enter new survey site information to do so.

Go back

16. Can I go back and correct errors in my habitat descriptions?
Absolutely! Just select the study site you would like to modify from the drop down menu, then click on the "Describe Habitat Characteristics" button. All of the current information about that particular study site will be displayed, and you will be able to change any of the fields necessary (except lat/long; see the previous FAQ,  #15, above).  Be sure to save your changes!

Go back

17. I tried to "add a site" to my list but it didn't work. What went wrong?
If this happens to you:

  • Refresh your screen (hit reload or refresh on your web browser) after adding your study site. This will allow your computer screen to retrieve the data that you submitted to the database.
  • If you are SURE that the site is not in your list, return to the "Add Study Site” feature and try again.

Go back

18. I've added a site, but when I try select study species I get an error message, "This location is outside of the BFL Study area, and is not useable in this project." What do I do?
When deriving a checklist from our database, the program looks at the state or region where the study site is located. If the study site is located in an area with out a checklist you receive the error message. It is likely the latitude and longitude are not within an area with a checklist. Delete the study site, re-calculate your latitude and longitude, then try creating the study site again.

Go back

19. How do I set the proper "cache" settings on my computer?
As you surf the Internet, your computer temporarily stores a copy of each web page that you visit in its memory, better known as its "cache". This is usually helpful, because it reduces the amount of time it takes to load these pages the next time that you visit them. However, if a change has been made to a web page between visits, the page stored in your cache won't automatically update with the latest changes. This is especially true for our online data forms. To get the latest changes, the user has to load the page from cache, then click "Reload" or "Refresh" so that the page is uploaded from the server, not from the user's cache.

Because the BFL web pages are updated frequently, it is important to set up your computer to grab our latest changes. Below are instructions for checking your cache settings.

Microsoft Internet Explorer Users
If you own a PC, go to "Tools/Internet Options" on the main menu bar. Then, under the General tab click on Settings for temporary internet files. Be sure that the option to "Check for newer version of stored pages" is set to "Every visit to the page."

If you own a MAC, go to Edit/Preferences from the main menu bar. Click on "Advanced" and make sure the Cache Updated selection is set to "Always."

Netscape Users
If you own a PC, go to Edit/Preferences from the main menu bar. Then, under "Advanced/Cache," make sure that "Document in cache is compared to document on network" is set to "Every time."

If you own a MAC, go to Edit/Preferences. Then click on "Advanced" in the left column to view subcategories. Cache will show as a choice. Click on "Cache" and make sure that "Once per session" is selected.

If you find that changing your cache settings slows down your Internet connection too much, you may return to your original cache settings for general web surfing, but you really should either hit "Reload" or "Refresh" on each of our online data entry pages that you visit. If this is too cumbersome, then another option is to use our recommended cache settings during each visit to our site. These latter options require you to fiddle with your pages or your settings on each visit, but it is very important that you get the latest changes to our web pages.

20. How do I determine which web browser I'm using?
The BFL web site was programmed to work with the most widely available web browsers (click here for supported browsers). However, each web browser functions slightly differently on different computers, so you may encounter problems that are unique to your computer set up. To help us troubleshoot what your problem is, we need to know the exact web browsing software you use and what operating system is installed on your computer.

To find which web browser you use, go to the main menu bar of your web browser, and select the HELP menu option. Then scroll down to "About." This calls up a window that describes your browser, including the browser name (e.g., Netscape or Microsoft Internet Explorer) and its version number (e.g., Netscape 4.01). Please give our staff the exact version number that appears in the "About" window, for example, Netscape 4.01 or 4.06. It is not sufficient to say 'Netscape 4.'

Also, please tell our staff what computer operating system that is installed on your computer (e.g, Windows 95, Mac OS 8, etc.).

Go back

21. How do I determine which operating system is installed on my computer?
Finding which operating system is installed on your computer will depend on what type of computer you are using.

Macintosh Users
On the top of your screen is your web browser's menu bar, where you should see choices such as File, Edit, Favorites, Help, etc. On the far right of that menu bar is the name of the program you have open (if you have your web browser open, it likely reads "Internet Explorer" or "Netscape Navigator"). Click on the name of the program, then select "Finder" from the drop-down menu that  appears. The word "Finder" should be displayed in the upper right-hand corner.

In the upper left-hand corner of your screen is the Macintosh Apple logo. Click on the apple, then select "About This Computer" from the drop-down menu that appears.   A small window will open up displaying information about your computer, including the operating system and version number (e.g., "Mac OS 8.6").

PC Users
Minimize any programs you have open so you can see your desk top. Right click on the "My Computer" icon and select "Properties" from the drop-down menu that appears. A window entitled "System Properties" will open up, displaying information about your copmuter including the operating system and version number (e.g., "Microsoft Windows 98 4.01.1998").

General BFL Questions
1. What kind of CD player should I buy?
We don't recommend a particular brand and model, because model numbers and specifications change so frequently. Any name brand portable CD player should be fine, as long as you can reproduce the sounds at a realistic level. If you use a personal CD player, you will need to get a speaker for it. Small, inexpensive, amplified speakers are available from Radio Shack (model number 277-1008, for example) and other stores.
