Baby pigeon mystery.
My pigeon book is here: www.hachettebookgroup.com/titles/rosem...
A six-panel comic. In panel 1, text says "People often wonder, why don't I see baby pigeons? Here's where they're hiding:" and there's an egg with an arrow pointing to a question mark, then an arrow pointing to an adult pigeon. Panel 2 says "Pigeons don't nest in trees. They nest in sheltered spaces on or in buildings. This keeps their babies safe from weather and predators." There's a pigeon nesting in a sheltered cavity in the side of a building. Panel 3 says "The hidden babies look like this: like moldy potatoes, but cute" and there are two baby pigeons looking, well, like moldy pink and gray potatoes with yellow fuzz. Panel 4 says "Older baby pigeons hide in plain sight. When they leave the nest, they're adult-sized, but they're still young and learning" and a fledgling pigeon is flying out of a building saying "aaaaaa". Panel 5 says "Here's how to identify these young pigeons" and shows a fledgling pigeon with arrows pointing to these features: eyes may be gray-brown, pale-edged feathers, smaller "nose" (cere), subdued hues, and looks worried. Panel 6 says "Scientifically speaking, though, all pigeons are sweet babies" and there are three very cute round pigeons, a gray, white, and red one, with arrows pointing to them to make things look scientific.

Did you ask for a bird fact? No, but you're getting one whether you like it or not. 🪶
Photo of a Juniper Titmouse by Wendy Miller. Text on the graphic says "Unsolicited Bird Fact: Female Juniper Titmice don't scare easily. When a predator approaches an incubating female on the nest, she doesn't flee- she hisses like a snake. Researchers in the 1940s checking nests noted that females often had to be removed the nest by hand in order to see the eggs. This bravado may work well when dealing with Woodhouse's Scrub-Jays, who frequently raid Titmouse nests to eat the eggs or nestlings.

Did you ask for a bird fact? No, but you're getting one whether you like it or not. 🪶
Photo by Daniel Mennerich of a Rhea crossing a road in Germany. and illustration of a cuckoo against a clockface has a speech bubble with the cuckoo saying "Warum überquerte der Nandu die Straße?" Which means why did the Rhea cross the road in German. Text on the graphic says "Unsolicited Bird Fact: In the early 2000s, several Rheas escaped from captivity in NE Germany, and established a feral population. By 2018 that population had grown to 566 birds and was wreaking havoc on farmers' crops. Eventually, local authorities opened a hunting season on the birds & it seems the population has now declined. Meanwhile, Rhea populations in their native range in South America are declining at a concerning rate.
