Chicken in a tree

Red Junglefowl / Feral Chicken (Gallus gallus) Domestic chickens descend from the Red Junglefowl, and feral populations worldwide revert to ancestral habits like roosting in trees — exactly what this rooster is doing. Free-ranging and feral chickens are a common sight across the tropics, thriving anywhere warm weather and scattered food let them nest and roost in the open.

Black squirrel in a tree

📍 San Mateo Eastern Fox Squirrel (Sciurus niger) North America’s largest tree squirrel, it spends more time foraging on the ground than most tree squirrels and scatter-hoards nuts across dozens of small caches to get through winter. Melanistic individuals are usually rare, but in parts of San Mateo they are so common that an all-black coat is practically the local norm rather than the exception.

📍 San Mateo Eastern Fox Squirrel (Sciurus niger) The all-black coat comes from a recessive melanistic variant that switches off the usual rusty-orange pigment, leaving individuals uniformly dark from nose to tail. Fox squirrels are not native to California — they spread across the Bay Area after introductions in the early 20th century and now outnumber the native Western Gray Squirrel across much of San Mateo’s parks and neighborhoods.
