The Puerto Rican tody (Todus mexicanus) is a small, brightly colored passerine bird endemic to the island of Puerto Puerto Rico. It belongs to the family Todidae, which comprises the todies, a group of small insectivorous birds native to the Caribbean. The species was first described scientifically by Johann Friedrich Gmelin in 1789.
Taxonomy

- Species: T. mexicanus
Physical description
The Puerto Rican tody measures approximately 10–11 cm (4.0–4.3 in) in length and weighs about 5–7 g. Adults exhibit a bright green dorsal plumage, a bright red throat and breast, and a black mask extending from the beak to the eye. The wings and tail are dark with white markings on the wing coverts. The bill is short, stout, and slightly hooked, adapted for catching insects.
Distribution and habitat
The species is confined to Puerto Puerto Rico, where it occupies a variety of forested habitats, including tropical rainforests, subtropical moist forests, and secondary growth in both lowland and montane regions. It is most commonly observed in the Luquillo Mountains and the central mountain range, but it can also be found in coastal forest fragments.
Behavior and ecology
- Diet: The Puerto Rican tody feeds primarily on insects and other small arthropods, such as beetles, flies, spiders, and caterpillars. Foraging occurs by sallying from perches to capture prey in mid‑air or by gleaning from foliage.
- Territoriality: Males defend small territories year‑round, using vocalizations and displays to deter rivals.
- Vocalizations: The bird’s song consists of a rapid series of high‑pitched “tsee” notes, often delivered in a trill. Calls are used for communication between mates and for alarm.
Reproduction
Breeding occurs from March to July, coinciding with the island’s rainy season. Nests are constructed in shallow cavities excavated in soft wood, often in dead branches or in the trunks of trees such as the Puerto Rican oak (Lithocarpus trichophyllus). The female typically lays 2–4 white, unmarked eggs. Both parents share incubation duties, which last about 16 days, and both feed the nestlings. Fledging occurs roughly 19–22 days after hatching.
Conservation status
The International Union for Conservation of Nature (IUCN) classifies the Puerto Rican tody as “Least Concern” due to its relatively wide distribution within the island and its ability to tolerate some habitat modification. However, ongoing threats include deforestation, habitat fragmentation, and the impacts of hurricanes, which can temporarily reduce suitable breeding sites.
Cultural significance
The Puerto Rican tody is a recognizable symbol of the island’s avifauna and is featured in local birdwatching guides and ecotourism initiatives. Its vivid coloration and distinctive behavior make it a popular subject for educational programs about Puerto Puerto Rico’s endemic wildlife.
