Eastern Kingbird

Tyrannus tyrannus

Tyrannidae

The bird that will attack a Red-tailed Hawk. Eastern Kingbirds are aerial insect hunters with an outsized attitude — they'll chase crows, jays, and larger raptors out of their territory in mid-air, sometimes riding on the raptor's back. Sharp black-and-white plumage with a hidden red crown patch. Undergoes one of the most dramatic diet shifts of any NJ bird.

Arrives in May; departs September for South American winter grounds.

Identify by

How to spot one.

  • 7.5–9 inches — larger than a sparrow, smaller than a robin

  • Blackish upperparts, clean white underparts

  • Black tail with a striking white terminal band

  • Small head with a hidden red crown patch (rarely visible)

  • Often perched upright on a fence post, wire, or exposed branch

Voice

What it sounds like.

A rapid, sputtering 'tzee-tzee-tzeetzeetzee' — sounds mechanical, like a small motor turning over.

Life & behavior

How it lives.

Sallies out from exposed perches to catch flying insects, then returns to the same perch. Fiercely territorial — a mated pair will chase away everything from other Kingbirds to hawks. Nests on horizontal tree branches near open areas.

Diet

What it eats.

Diet often shifts dramatically between breeding season and the rest of the year — especially for insectivorous birds that pivot to native berries in fall and winter.

Summer / breeding season

  • Flying insects: bees, wasps, beetles, dragonflies, flies

  • Grasshoppers, cicadas, moths

  • Almost exclusively insectivorous in NJ breeding season

Fall / winter

  • Migrates to Amazon basin, tropical South America

  • Dramatic shift: winter diet is nearly all fruit — figs, palm fruit, native tropical berries
