Interesting to read (on Cornell's website) that apparently rock pigeons were introduced to North America from Europe in the early 1600's.

LOL according to the Journal of the Experimental Analysis of Behavior

Pigeons' discrimination of paintings by Monet and Picasso

Abstract

Pigeons successfully learned to discriminate color slides of paintings by Monet and Picasso. Following this training, they discriminated novel paintings by Monet and Picasso that had never been presented during the discrimination training. Furthermore, they showed generalization from Monet's to Cezanne's and Renoir's paintings or from Picasso's to Braque's and Matisse's paintings. These results suggest that pigeons' behavior can be controlled by complex visual stimuli in ways that suggest categorization. Upside-down images of Monet's paintings disrupted the discrimination, whereas inverted images of Picasso's did not. This result may indicate that the pigeons' behavior was controlled by objects depicted in impressionists' paintings but was not controlled by objects in cubists' paintings.

Snapped this Rose-ringed Parakeet after feeding the crows on our walk this morning.

We only started seeing the parakeets here a few years ago but they've been increasing in numbers and spreading further. They're quite easy to spot due to the noise :D .

Came upon a Blue Heron while walking the pups this morning.

Excellent!  About how far away were you from it and what did you use to take the photo?

PD

p.s.  I've given up trying to take photos of birds (I have an old iPhone).   :(

I used my iphone and was reasonably close, but up a river bank. Luckily, my dogs were quiet so the heron didn't feel threatened.

My phone is old, too. It's the iphone XR, which I think came out right before the iphone 11.
