Oporornis agilis
male
The Connecticut Warbler is a plump-bodied songbird. The sexes are dissimilar. Adult males have an olive-buff back, wings, and tail. The head has a gray hood, palest on the throat and darkest on the well-defined lower margin, and a white eyering. The underparts are otherwise bright yellow. Adult females are similar to adult males but less colorful overall and with a browner hood. Immatures are similar to an adult female but the hood and upperparts are buffish brown. The legs are pink in all birds.
The Connecticut Warbler is present as a breeding species in northern forests mainly from May to August. It spends the rest of the year in South America. Typically, it forages on the ground. Its secretive habits, combined with the relative inaccessibility of its favored habitats, mean it is hard to observe. Its presence is easiest to detect by listening for its song.
