Birds




Acorn Woodpeckers


Acorn Woodpeckers of the Western US and Mexico store acorns in "granary" trees and defend them aggressively.  They wedge the acorns into holes in trees or wooden telephone poles so tightly that crows, squirrels, and rats can't raid their supply. 


To remove an acorn, a woodpecker hammered it with its bill to crack the shell and extract the meat.




Florida Scrub Jay





These birds cache food by burying one acorn at a time;  if they observe another jay, a potential cache robber, watching them, they will return later to move the acorn.
But they will only do this if they themselves were cache robbers in the past.  Seems that honest jays trust other ones and thieves do not.







Western Scrub Jays are very similar in appearance to our FL Scrub Jays

Great Blue Heron






The largest heron in North America




They eat mainly fish but we have seen them eat rats, small sting rays, snakes, lizards, rabbits, and other small animals.





Male House Sparrow





These birds return to their birthplace after each migration (a characteristic known as philopatric).  Because of this, local populations have adapted to the color of their habitat resulting in 15 distinct subspecies in the West.

Unlike Bald Eagles, Ospreys can become completely submerged during a dive into water and are still able to fly away with their prey.





Their oily and dense plumage provides water proofing.

Black Skimmers at North Shore Beach: 1-5-18

Black Skimmers with Forster’s Tern







The Black Skimmer has one of the most unusual forging styles of any North American bird.



A feeding skimmer flies low over the water with its bill open and its lower mandible slicing through the water.





When the mandible touches a fish, the upper bill snaps down instantly to catch it.
