Brown Jays
Jay Information ... Jay Photo Gallery
The Brown Jay (Cyanocorax morio) occurs from Mexico south into Central America on the Gulf slope.
Description
This is a large Jay which has the look of a Magpie about it, but is slightly smaller and with a shorter tail, though the bill is larger.
Brown Jays vary in plumage geographically: there are two main groups. Northern birds are almost completely dark brown, with lighter brown on the underparts. Southern birds are white-bellied and have bright white tips to the outer tailfeathers. The intergrade zone is in Veracruz.
Adults in both populations have black bills, legs, and feet. Immatures have yellow bare parts, including yellow eye-rings.
Diet / Feeding
Food is sought largely in trees but it also takes some food from the ground. Insects and a wide range of other invertebrates (= animals without internal skeleton, such as insects, larvae, earthworms, millipedes, snails, spiders) are taken, also lizards, fruit, and nectar.
Though it does take eggs and nestlings, it appears not to if there is plenty of other foods available.
Nesting / Breeding
The nest is built in a tree or large shrub with both sexes helping in construction. There are normally three eggs laid but six is not unusual. Incubation is between 18 and 20 days. Only the female broods but the father feeds her while doing so.
Sometimes the young from another year will help in raising the chicks too. If a helper bird returns with food, it will give it to one of the resident parents to feed the chicks.
Calls / Vocalization
The voice is a loud but low pitched pee-ah call and is often modified to suit its situation or mood.
