Azure-hooded Jay
Cyanolyca cucullata
The azure-hooded jay ranges in length from 11 to 12 inches (28 to 30 cm), and it tends to weigh 3.52 ounces (100 g). Its large size and frame help the bird manage the large amount of flying it does. The adult is dark blue with black on the head and upper chest, while the rear of the crown and nape, or back of the neck, are sky blue with a white border. The legs and bill are black and the eyes are dark red. Both sexes are similar in appearance. Juveniles are duller than adults and their sky blue hood does not possess the white bordering.
