I almost never buy books on paper, but Omnibird: An Avian Investigator's Handbook by Giselle Clarkson (author and illustrator) was an instabuy for me. 📚

Omnibird investigates 18 common birds from habitats around the world―eagles, owls and seabirds, starlings, ducks and swans. Explore the incredible internal structure of bird bones, learn what a gizzard stone is for, find the fascinating in bird calls, bird poop, feathers, and flight patterns.

The text and especially illustrations grabbed me.

Book cover shows a hybrid bird with a long white neck reaching backwards. The style is humorous and cartoony.
Two internal facing pages show a fat white bird on one side saying Ahem, and on the other a white swan-like bird with a very long neck reaching all the way back beneath its body in a kind of extreme yoga pose. The style is humorous and cartoony.
An internal page shows various birds that seem like penguins but are not. The style is humorous and cartoony, as is the text.
