The adult male and female Hooded Orioles look different, with juvenile birds looking like the female until male characteristics grow in. This is typical of many species, which makes determining the sex of juvenile birds very difficult, if not impossible, at times. You may hear the term 'female type' now and then, which applies in situations like this where the bird looks like an adult female but might be a young bird of either sex.
