(14 May) I presume, given the fate of many of the other nests during this
period, that that is not an unlikely supposition) it is most likely
what they're being fed, not how much. If the weather is decent
tomorrow, this nest should be checked then.
15 May 1500. Weather is sunny but still cool and windy. Watching the nest.
♀ in hole. Came out when ♂184 gave 1st feeding.
1) ♂184. → in hole 2) ♀265 see below * stayed to next feeding (in hole)

1700. Leaving. Total feedings: 36, 18/hour - certainly a
good clip. Most of what they were feeding was apparently
insects, also. Conditions are obviously improving.
16 May 900. Cold and cloudy. Watching hole. ♂ in hole at 859.
Feeding: 902(♀265); 905(♂184 Acorns); 909(♀269); 910(♂?); 911(♀265); 913(♂184);
