Notes:

4.76

avg young per nesting attempt

>= indicates there were greater than or equal to the number of eggs listed (eggs hidden far beneath leaves were difficult to count)

* April 24th - female sitting on eggs in Natural Gourds #1 during nest check, egg count not taken

* April 29th - Natural Gourd #12 added

* May 4th - did not check many nests today, installed 2 predator guards and didn't want to keep females away from incubating too long

* May 8th and onward - decided to spread out nest checks to keep from interrupting incubation and feeding for too long at once

* May 12th - female sitting on eggs in Natural Gourd #4
