1980 R.L. Munroe 5 Melanerpes formicivorus Road 1 Hastings Reservation (19 April) 0731, ♀269 at nest, 0732 flies off. ♂486 enters briefly, follows ♀269 0734 ♀269 enters, ♀383 arrives, uukling, looks in, flies off. ♂486 visits briefly, 0739 ♀269 leaves **** 0744, Scineludy enters nest! 0745(?)Bird flies out of nest carrying a- egg! flies to Valley Out below huu and across #heroad from the secondary sycamore granary, just below the main granary. I do not see the Bird drop the egg there (nor do I later find remains under that branch along the road). Trying to scope the bird, I lose it. Extreme profanity and frustration follows. I believe the bird was ♀383, but I do not know for sure. My reasons for believing thus are as follows: ① It was not ♂486. I had him in sight in the top sycamore adjacent to nest of the granary while the mystery bird was in the nest. ② After losing the "tosser" I tried to find the other birds. There was confusion, and it is entirely possible that the tosser could have snuck back but the first 3 birds I picked up in the nest area were ♂486, ♂294, ♀269. ③ ♂284 has yet to enter the nest, and he visits it rarely ④ If the mystery bird were ♀269, I'm sure ♂486 would have followed her! Instead, he remained in the Sycamore adjacent to the nest. In my entire 6 hour watch, I do not think I saw ♂486 more than
