What colors can birds not see?
While humans have just one nonspectral color—purple, birds can theoretically see up to five: purple, ultraviolet+red, ultraviolet+green, ultraviolet+yellow and ultraviolet+purple. Stoddard and her colleagues designed a series of experiments to test whether hummingbirds can see these nonspectral colors.
Do birds recognize humans?
Newsletter. Antarctic seabirds called skuas are so clever that they can recognize individual humans after seeing them only a few times. Some Korean researchers discovered this by messing with the birds’ nests and then waiting to get attacked.
