s. Males and females can be distinguished by the coloration of their eyes: males have gray eyes while females have white eyes.
Todies are hard to spot visually but are easily identifiable by the loud nasal beep they make. Also known as
papagallo, they make their nest on the face of cut ground (e.g., in road cuts created during road construction). Another way you could find their nests is on a hill side. Todies never nest in trees or man-made structures. They are active in the daytime, and mostly frequent forested habitats.

Diet
The Puerto Rican Tody is an insectivourous bird although it has been observed supplementing its
hatchlingIn oviparous biology, a hatchling is the newborn of animals that develop and emerge from within hard-shell eggs. The offspring of birds are often hatched naked and with their eyes closed. The hatchling relies totally on its parents for feeding and warmth. Hatchlings precede nestlings in the chick's...

(Diptera), and beetles (Coleoptera), as well as spiders, and occasional small lizards. Todies are considered voracious eaters.
Todies sit quietly on high perches and scan the surface below with fast, jerky motions of its bill which it has the habit of tilting towards the sky. Once it find its prey it will suddenly take flight, grab the insect and sit on another perch.
Reproduction
The Puerto Rican Tody has an unusual nesting technique. The male and female todies excavate a long, narrow burrow in an earth bank ranging from 25 to 35 cm in length. They create their nest at the end of this burrow. This process occurs from February to June, before the start of the wet season. Females then lay from 1 to 4 bright white eggs, with an average of 2.3 eggs. Both the male and the female incubate the eggs. The incubation period has an average of 21 days. Other adult todies may assist in the development process of the chicks.
Unique features
The Puerto Rican Tody has been researched extensively because of its unusual body temperature, body temperature control and temperature control abilities. Puerto Rican Todies exhibit lower body temperatures than other todies and have also exhibited heterothermy over a range of temperatures . Most
