First I want to thank all the people that e-mailed me. The over whelming
response to the Eastern Bluebird question yesterday was, getting food. Here is
What one person had to say : Your paper wasp nest looks like a White-faced
(bald-faced) Hornets nest. They do not hibernate in the nest over the winter
so there is little danger to the bluebird. There may be some dried young in
cells that the Bluebird is after, but I would think he/she is looking for either
insects that might have recently inspected the nest or hiding in the nest (e.g.
spiders, flies, etc.) or is looking for nesting material.
I have over the years gathered these nests after the first hard freeze which
kills off any Wasp/Hornets that haven’t gone to hibernate in the ground. I
asked my friend Harry who found the nest, if he had a better photo of the bird
on or in the nest , but his was no better then the one I posted yesterday.. So
there you have it looking for food..see original post for link to image of the
nest and the hole the Bluebird was using.
Thanks again and good birding!
