A real field recording of the Tropical Kingbird, made in the wild.
A tropical kingbird can be as long as a school ruler, measuring 22 cm (8.7 in) from tip to tail, while weighing just 39 g (1.4 oz) and spreading its wings to a span of 38-41 cm. The same species is reported to range from 18 to 23 cm in length, weigh 32 to 43 g, and have a wingspan of about 12 cm, showing slight variation across its vast range.
Tropical kingbirds stay with one mate for life, building a bulky cup nest up to 20 m (66 ft) high in a tree fork. The nest measures about 13.2 cm (5.2 in) across and 7.6 cm (3.0 in) tall, with an interior cup 7.6 cm across and 4.1 cm deep. The female lays two to four speckled eggs, incubates them for roughly 16 days, and the chicks leave the nest after 18-19 days. This rapid development means the pair can raise a new brood each season, keeping insect numbers in check across their extensive territory.
From a high perch, the kingbird darts out to snatch insects mid-air, a hunting style called hawking, and can even hover to pick bugs off leaves. Its menu includes beetles, bees, wasps, termites, butterflies, moths, dragonflies and grasshoppers, plus occasional berries from trees like guava and gumbo-limbo. By devouring both pest insects and spreading seeds from the fruit it eats, the bird helps farmers control crop-damaging bugs while also planting the next generation of native plants.
The tropical kingbird has a global breeding population estimated at around 200 million individuals. Because it thrives in open forest, edges, scrub and farms from the southwestern United States to Argentina, the IUCN lists it as Least Concern and rates it only 4 out of 20 on the continental concern scale.
When a larger bird like a magnificent frigatebird or a toucan swoops nearby, the kingbird will dive, dip and dodge, even mobbing the predator in groups. Known predators include aplomado falcons, swallow-tailed kites and chestnut-mandibled toucans.

In the sweltering heat of the tropical realm, the Tropical Kingbird reigns supreme, its sleek, gray plumage glistening like polished stone as it patrols the sun-drenched skies with effortless ease. With a flick of its forked tail, it darts and weaves through the dense foliage, its sharp, black eyes ever-vigilant for the slightest hint of movement, as it pursues its insect prey with lightning-fast precision. As it alights upon a branch, its melodious song erupts into the air, a joyous, whistled serenade that echoes through the forest, a testament to the unbridled vitality of this avian monarch.
