C. c. bromia (eastern Canada and northeastern United States)
C. c. cristata (central and eastern United States)
C. c. semplei (Florida)
C. c. cyanotephra (central and southern Mexico)
Body Strength:
Blue Jays are strong fliers and can reach speeds of up to 25 miles per hour (40 km/h). They are also able to lift and carry objects up to three times their own weight.
