"Across 1520 species of birds, higher temperatures are associated with longer wing bones, as predicted by Allen's Rule... we interpret the positive relationship between temperature and wing-bone length to reflect increased demand for heat dissipation in warmer climates. Our findings highlight the role of thermoregulation in shaping even the most critical features of vertebrate anatomy."

Here's a great list of great birds!
en.wikipedia.orgList of individual birds - Wikipedia
"Interaction with ants has been recorded in 1122 bird species (11.2% of extant species) belonging to 131 families widely distributed across the globe and the avian phylogeny. On the other hand, 47 genus of ants (14.4% of extant genus) belonging to eight subfamilies interact with birds. Interactions include competition, antagonism (either ant–bird mutual predation or parasitism) and living together commensally or mutualistically."

Coz while I captured the critter bird, a gold finch I believe, some time in the last year or so, I only processed it last night. So ... 2024 Besides, I had to make a couple of small changes in Light room.
Jordan While on my walk today, I saw this bird!
I think it's a hawk of some sort?
Anyone know it's species? 
Humans May Have Driven Twice as Many Bird Species to Extinction as Previously Thought

Custom rubber stamp made for @hr_bananabird with the same design as their wax seal (see older post).
I’ve included pictures of the production process for this one! ^.^

Interesting sounds. Yes it’s imitating some dog sounds too.

This beautiful Florida resident, the Great Egret (Ardea alba) with wings still outstretched, has just touched down on a wooden pylon at a dock on the bay. They are such graceful birds, especially when in flight and their white feathered wings always remind me of angels.

Photographed this handsome Great Blue Heron wading the dark waters of a local botanical park lagoon. The lighting was perfect to show off his beautiful plumage and reflections.
