Being a people/lifestyle photographer, this seems a bit off brand and off topic, but during the first pandemic lockdown in Lisbon, back in 2020, I had nothing better to do, so I took an interest in a family of blackbirds that nested in a treetop near my window.
My two cats also took a (very keen) interest in them... so much so that the male blackbird had to go into battle mode and chased them away from the balcony every time he saw them!
I now live in a different location, far from that neighbourhood, and yet my cats are always on high alert every time they hear a blackbird sing.
