About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
