Thought it was Ivy grabbing some time but wasn't sure til 30 seconds later the squawking started and in she came. He tried to stay an extra second but then off he went.
Even with all TPC's excellent explanations, I still have trouble telling them apart unless I see them together. I thought the bird that came in the nest had neon white but them once he was on the chicks the white seemed blurry.
Different ID rules for Brandon and the Radisson ...
at the Radisson check out the heads - if you can see any light coloured feathers on the head (mostly at the back and nape of the neck) that is Princess. If the head is fully black, that is Ivy.
in Brandon, Brooklyn the male is neon white on his breast and cheek patches, Hurricane's cheek patches are more blurry and she isn't that neon white colour.
Hope this helps!
