Verdugo gorjinegro Cracticus nigrogularis

Medium-sized ambush-hunter with a long gray bill with a dark, hooked tip. Adult has black head, upper breast, back, and tail that contrast starkly with white nape, breast, belly, and wing pattern. Immature similarly patterned in brown instead of black. More likely than Gray Butcherbird to perch atop trees and poles. Beautiful fluting, whistling song, sometimes heard at night.
