22 April An interesting watch here, despite my suffering from frozen
feet (cold and very wet). It looked to me that, as egg-laying
would down and incubation began in [scribbled] earnest,
the well-marked
pairs of the past two days began to break down. ♂486
initiated flights away from the ♀269, and even failed to
follow her once or twice. He was also spending longer periods in
the nest. Furthermore, ♀269 seemed especially conciliatory
towards ♀294, opening waiting to him at least a
few occasions. Certainly something to take data on in
the next week or two.
0500 watch starts
0510 ♀ head out of roost hole flies off
[scribbled] Forget all that crap! Also should note that
I saw ♂294 ♀269 joining in crow mobbing with ♂294.
I really need to get data on "pairing" in these guys, soon.
23 April 5hrs + of nest watching from the road on this rainy day.
Talk about enthusiasm! 3 birds in the nest at once on some occasions
