Cam Highlights:

|
July 19 - Shortly after the bluebird left the nest box, the House Wren returned
for a visit. |

|
July 18 - The only visitor to
this nest box today was this bluebird that stopped in briefly.
We'll have to wait and see which species claims the box.
|

|
July 17 - A House Wren shows some interest in this nest box as it returns a
second time. |

|
July 15 - A House Wren made a surprise appearance in the nest box today! |



|
July 3 - Much earlier than we
anticipated, these bluebirds fledge today at only 16 days old! Typical
nesting periods for Eastern Bluebirds last between 18 and 21 days.
Starting from the top image, the camera captures the birds as they fledge the nest within about three hours of each other!
|

|
July 2 - As one nestling shows off its beuatiful juvenile plumage, another vocalizes in the nest.
|

|
July 1 - At 14 days old, the young birds start to spread their wings and practice flying in side the box.
|

|
June 30 - Here is a shot of the female in the nest with the 13-day old
bluebird nestlings. Notice how similarly colored the young are to the adult.
|

|
June 29 - Now twelve days old, the nestlings are almost completely feathered.
|

|
June 28 - Despite the heat and viewer comments about the health of the nestlings, they all appear to be developing normally.
|

|
June 27 - Notice the fine down feathers on the head of this hungry bluebird
nestling. |

|
June 25 - Check out the beautiful coloration on this male bluebird as he returns to
feed the nestlings. |

|
June 24 - With beaks wide open, all four bluebird chicks anticipate the return of the adults with their next meal.
|

|
June 23 - At six days old, the young birds are still featherless over half their body.
|

|
June 22 - This looks like a quite a mouthful for a nestling!
|

|
June 21 - The male delivers what appears to be a small moth to the five-day old nestlings.
|

|
June 20 - One of the begging nestlings is being offered what looks like a delicious grub!
|

|
June 19 - At three days old, the nestlings can do little
more than hold there necks up and beg for food.
|

|
June 17 - Just as predicted, all four eggs hatched between yesterday and today!
|

|
June 16 - We have been watching
three nestlings and one egg since dawn! The female has spent much of
the day in the nest box, though here we get a good look at the
nestlings.
|

|
June
13 - Although clutch sizes are typically smaller for second nest
attempts, there is no difference between the actual size or mass of
eggs among early and late clutches.
|

|
June 11 - This female has shown
a very consistent pattern of on and off bouts—on the eggs for about 25-30
minutes, off for about 5-10 minutes.
|

|
June 10 - Just one more week of incubation to go!
|

|
June 7 - The female was seen
with her mouth open for much of the day. She could be
vocalizing to her mate, or panting as a way to keep herself from
overheating.
|

|
June 5 - The female is in her second day of incubation.
Although it seems like a very passive activity, incubation requires a large
amount of energy on the part of the female. |

|
June
3 - Most females typically lay very early in the morning. This female
laid the fourth egg mid-morning, as she did the three previous eggs
from this clutch.
|

|
June 2 - The third egg was laid nearly 24 hours after the second.
|

|
June 1 - A little later in the morning than expected, the second egg was laid.
|

|
May 31 - Just four days after seeing the female
in the box for the first time, we are pleasantly surprised to see the first
egg! |

|
May 29 - With nest material in her beak, the female bluebird carefully weaves the nest cup to her liking.
|

|
May 27 - The female is seen forming the nest
cup, a good sign that another nest attempt is in progress.
