Banana or Bird?

Bucerotidae

by Inspector Barry Mins on December 20, 2022

Hey kids, welcome back to our series on the mysteries of created kinds. Last week we met a diverse kind of medium-size mammal. This week we’re moving on to birds with feisty tempers and loud voices.

Two by Tuesday

These birds are found throughout Africa and south Asia. They tend to live in forests, preferably ones undisturbed by development, though they will use human gardens when needed.1 Larger, more established trees are preferred.2 Home ranges vary depending on the species and the time of year.3 Some species also migrate to new areas to breed.4 When foraging, they are alert to other species around them, monitoring alarm calls from other organisms. They can even determine from the alarms whether the predator is threatening to them or not.5

This kind is largely omnivorous but finds fruit particularly appealing. Figs are a major part of some species’ diets.6 Other species are more aggressive, raiding the nests of other birds.7 On occasion, they will even kill one of their own chicks that is not developing and feed it to the other chicks.8 Other species include lizards and invertebrates in their diet.9 Because they eat so many fruits, many of this kind serve as excellent seed dispersers for plants.10

When this kind mates, the females will build the nest and then seal themselves inside.11 Males will then bring food to the females and hatchling chicks an average of nine times a day!12 Occasionally, they will have two broods in one mating season.13 Males will fight for the right to mate. At least one species will go so far as to engage in arial jousting matches where they butt their specialized casques against each other.14

Has anyone figured it out yet? This week’s kind is the Bucerotidae—the hornbills. You have probably seen an example of these birds in your local zoo or aviary. If you have, you know they are loud! Stay tuned for next week when we start looking for a small family of amphibians.

Clue

Your clue for the week is:

These toads get their name from the shape of their hind legs which they use for burrowing.
