Red-tailed Hawk (Buteo jamaicensis)
Scream: The common call of the Red-tailed Hawk is a variable, harsh, hissy scream, lasting several seconds and very gradually
descending. The scream is usually given in the air, but also occasionally while perched. It is frequently given during
territorial disputes and may also be elicited by the too close approach of a human (Fitch et al. 1946).
