Four Purple Martins Hatch

In the first gourd, four of the five eggs hatched. Two of them early last Wednesday, the other two late on Thursday. The older two have the beginnings of darkening on the spine and rump from feather growth. They are now mobile enough to squirm a bit out of the nest cavity.

The fifth egg did not hatch and the female has not been trying to incubate it anymore. I removed it yesterday evening during the nest check. The pipping marks thought I saw in the video turned out to be dirt. There is no evidence of an attempt to hatch. It is shown below in comparison with a House Sparrow egg removed from gourd #7 (lower level to right of #1) along with the adults.

May 13 - Chicks progressing, oldest chick is a little over 9 days old.

May 23 - Oldest is now 13 days.
