What's the difference between a blue jay and a California Scrub-Jay?

The blue jay and the Florida Scrub-Jay are both members of the jay family, but they have several distinct differences in terms of their appearance. One of the most noticeable differences is the presence of a crest on the head of the blue jay, which the Florida Scrub-Jay lacks. The crest is a prominent feature, with feathers standing upright on the top of the blue jay’s head, giving it a distinctive and striking look.

Another key difference lies in their coloration. Blue jays have vibrant blue feathers on their backs, while the Florida Scrub-Jay has a grayish back. This blue coloration is one of the characteristics that make blue jays easily recognizable and gives them their name. Additionally, blue jays have a white wingbar, which is a distinct white patch on their wings. On the other hand, the Florida Scrub-Jay’s wings are plain and lack this white wingbar.

In terms of their behavior, both species are known for their intelligence and adaptability. Blue jays are often found in woodlands and suburban areas, while the Florida Scrub-Jay is restricted to the unique scrub habitats of Florida. This specialized habitat preference has led to the Florida Scrub-Jay being considered a threatened species, as their habitat is increasingly being lost to urbanization and development.

It’s also worth noting that both species have a varied diet, consisting of insects, fruits, nuts, and seeds. Blue jays are known to be particularly opportunistic feeders and have been observed eating small vertebrates such as frogs and lizards.

In terms of their vocalizations, both species are highly vocal and have a wide range of calls. Blue jays are known for their loud and distinctive “jay” call, while the Florida Scrub-Jay has a complex repertoire of calls that are used for various purposes, including communication within their social groups.
