Daily Highlights |
|
May 22 - A nice shot of the female with one egg left. |
|
|
May 21 - The last egg is still in the nest. |
|
|
May 18 - The female comes to the nest, but this is the only image of her today. |
|
|
May 17 - We hope that the last egg survives! |
|
|
May 16 - It is sad to report that just one minute ago, there were two eggs in the nest. |
|
|
May 15 - The female is still checking on the eggs but the time she spends in the nest box is decreasing. |
|
|
May 14 - Unfortunately, another egg
disappeared this morning. Two undeveloped eggs were found near the nest
box, decreasing the possibility that it was a predator and increasing
the possibility that the female bluebird may be removing non-viable
eggs. |
|
|
May 13 - Five minutes later, only
three eggs are visible. It is hard to know exactly what happened,
but predation is a likely cause, even though the box is outfitted with
predator guards. |
|
|
May 13 - Four eggs are easily seen this afternoon. |
|
|
May 12 - The male pays a welcome visit just before 9:00 am! |
|
|
May 11 - A great image of the female as she continues to incubate the eggs! |
|
|
May 10 - The average temperature of the eggs during incubation is approximately 34o Celsius or 93o Fahrenheit. |
|
|
May 9 - Scientists have observed that
the incubation period of Eastern Bluebirds in S. Carolina is shorter
for summer clutches than for eggs laid in the spring. |
|
|
May 8 - It has been approximately one
week since incubation started. Hatching should begin within the
next four to twelve days! |
|
|
May 7 - We received this image this
morning of only four eggs in the nest. It is still being
determined if one of the five eggs could have been a cowbird egg. |
|
|
May 5 - A cute image of the female as incubation continues. |
|
|
May 4 - A nice shot of the male peeking in on the eggs. |
|
|
May 3 - It appears that the clutch is
complete. Since incubation begins with the arrival of the
penultimate (next to last) or ultimate (last) egg, incubation likely
began two to three days ago. |
|
|
May 1 - The fifth egg was laid just before 12:00 noon! |
|
|
Apr. 30 - Our first image of the fourth egg! |
|
|
Apr. 29 - The third egg arrived at around 10:00 am! |
|
 |
Apr. 28 - The second egg was laid at about 10:30 am! |
|
|
Apr. 27 - The first image of the first egg came in at 11:00 am this morning! |
|
 |
Apr. 26 - Once the female decides the nest is complete, it will take her eight days or so to lay her first egg. |
|
 |
Apr. 25 - The construction of this bluebird's nest appears
to be nearing completion. Once a threatened species, bluebird populations have
been greatly improved by efforts to provide them with artificial
cavities, in the form of "nest boxes." |
|
 |
Apr. 24 - A bluebird's nest is
built exclusively by the female. Here her tail feathers are visible as
she exits through the nest box door after delivering some dried grass. |
