Hastings Reservation
(9 May) One I got a look at while he was eating catkins and was
♂ yel-DG / yel-DG #100.
17 May 930. Both ♂ x ♀ yel-Bike / yel-Bike #100 and ♀ Pub up just past Big Tree
foraging on catkins. I watched them for a minute before they
flew over to one of the trees along the fence line (actually part
of Keep Out).
24 May After Larry reported birds looking out of the hole in the granary
here the last couple times he'd been up here (20, 21 May) I
finally made it up here to check. And yes, they do have a nest.
They have at least 3 eggs (probably only 3 eggs), but I
couldn't be positive without gauging out half my wrist to make
it to the bottom of the hole.
25 May GOD. This time I sawed up the lining enough to reach
the bottom, but to no avail: the nest has failed and
there were no eggs or remains inside. Nearby were
birds, however, including an unbanded ♀ who is probably
the one who belongs here.
29 May 1045. Nobody seen here in passing.
2 June 1700. Bird flushed out of nest hole!
3 June 1050. None in the hole this time.
7 June 1030. ♀ in hole. Going up, there are 4 fresh eggs in the nest!
They're trying again!
10 June 1400. Flushed a bird from the nest hole as I went up to check
the nest, which still contains 4 eggs.
11 June 1610. Bird in nest hole.
