The todies are a family, Todidae, of tiny Caribbean birds in the order Coraciiformes, which also includes the kingfishers, bee-eaters and rollers. The family has one living genus, Todus , and one genus known from the fossil record, Palaeotodus .

Taxonomy and systematics

The todies were originally placed in the kingfisher genus Alcedo before being placed in the genus Todus in 1760 by Mathurin Jacques Brisson. They have been linked to a large number of potential relatives since then, including nightjars, trogons, barbets, jacamars, puffbirds, kingfishers, motmots and even some passerine species such as broadbills, cotingas and flowerpeckers. The todies were placed in their own order, Todiformes, before being placed in the Coraciiformes. [2]

Genetic analysis of the extant (living) species suggests that they diversified between 6-7 million years ago. The fossil record of the family is sparse, but three species of tody have been described from fossils found in North America, Germany and France, showing that the family was once more widespread than it is today. Species from the fossil genus, Palaeotodus , are larger than living species and may have been closer in size to the tody motmot. [2] [3]

The phylogenetic relationship between the six families that make up the order Coraciiformes is shown in the cladogram below. [4] [5] [6] The number of species in each family is taken from the list maintained by Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC).

Distribution and habitat

The todies are endemic to the islands of the Caribbean. These are small, near passerine species of forests of the Greater Antilles: Puerto Rico, Jamaica, and Cuba, with adjacent islands, have one species each, and Hispaniola has two: the broad-billed tody (Todus subulatus) in the lowlands (including Gonâve Island), and the narrow-billed tody (Todus angustirostris) in the highlands. [8] [9]

Description

Todies range in weight from 5 to 7 g and in length from 10 to 11.5 cm. They have colourful plumage, and resemble kingfishers in their general shape. They have green heads, backs and wings, red throats (absent in immature Puerto Rican, broad-billed, and narrow-billed todies) [8] with a white and blue-grey stripe on each side, and yellow undertail coverts; the colour of the rest of the undersides is pale and varies according to species. The irises are pale grey. They have long, flattened bills (as do many flycatching birds) with serrated edges; the upper mandible is black and the lower is red with a little black. The legs, and especially the feet, are small. [9] Todies are highly vocal, except that the Jamaican tody seldom calls in the non-breeding season (August to November); [8] they give simple, unmusical buzzing notes, beeps, and guttural rattles, puffing their throats out with every call. [9] Their wings produce a "strange, whirring rattle", though mostly when courting or defending territory in the Puerto Rican tody. [8]

Behaviour and ecology

Diet

Todies eat small prey such as insects and lizards. Insects, from 50 families have been identified in their diet, particularly grasshoppers, crickets, beetles, bugs, butterflies, bees, wasps, and ants, form the greater part of the diet. Spiders and millipedes may also be taken, as is a small amount of fruit (2% of the diet). [2]

Their preferred habitat for foraging is in the forest understory. Todies typically sit on a low, small branch, singly or in pairs, keeping still or stepping or hopping sideways. When they see prey moving on the lower surface of a leaf, they fly a short distance (averaging 2.2 m in the broad-billed tody and 1.0 m in the Puerto Rican tody), [8] diagonally upward to glean it. They may also take prey from the ground, occasionally chasing it with a few hops. Todies are generally sedentary; the longest single flight known for the broad-billed tody is 40 m. [8] [9] Their activity is greatest in the morning when sunny weather follows rain, and in March and September. [8]

Todies are highly territorial but will join mixed-species foraging flocks composed of resident species and migrants from North America, when they pass through their territories. [2]

Breeding

Like most of the Coraciiformes, todies nest in tunnels, which they dig with their beaks and feet in steep banks [9] or rotten tree trunks. [8] The tunnel is 30 cm long in the Cuban and narrow-billed todies, 30 to 60 cm in the broad-billed tody, [8] and ends in a nest chamber, generally not reused. They lay about four round white eggs in the chamber. Both parents incubate but are surprisingly inattentive to the eggs. The young are altricial and stay in the nest until they can fly. Both parents also care for the nestlings, much more attentively; they may feed each chick up to 140 times per day, the highest rate known among birds. [9]

Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species living in the tropical regions of Africa, Asia, and Oceania, but also can be seen in Europe. They can be found in deep forests near calm ponds and small rivers. The family contains 118 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests.

<span class="mw-page-title-main">Bee-eater</span> Widespread group of insectivorous bird species in the family Meropidae

The bee-eaters are a group of birds in the family Meropidae, containing three genera and thirty species. Most species are found in Africa and Asia, with a few in southern Europe, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All have long down-turned bills and medium to long wings, which may be pointed or round. Male and female plumages are usually similar.

<span class="mw-page-title-main">Coraciiformes</span> Order of birds

The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes, though in many kingfishers one of these is missing. The members of this order are linked by their “slamming” behaviour, thrashing their prey onto surfaces to disarm or incapacitate them.

<span class="mw-page-title-main">Coraciidae</span> Family of birds

Coraciidae is a family of Old World birds, which are known as rollers because of the aerial acrobatics some of these birds perform during courtship or territorial flights. The family contains 13 species and is divided into two genera. Rollers resemble crows in size and build, and share the colourful appearance of kingfishers and bee-eaters, blues and pinkish or cinnamon browns predominating. The two inner front toes are connected, but not the outer one.

<span class="mw-page-title-main">Motmot</span> Family of birds

The motmots or Momotidae are a family of birds in the order Coraciiformes, which also includes the kingfishers, bee-eaters and rollers. All extant motmots are restricted to woodland or forests in the Neotropics, and the largest are in Central America. They have a colourful plumage and a relatively heavy bill. All except the tody motmot have relatively long tails that in some species have a distinctive racket-like tip.

<i>Septencoracias</i> Extinct genus of birds

Septencoracias is an extinct genus of bird related to modern rollers and other Coraciiformes such as kingfishers, bee-eaters, motmots, and todies. It contains two species, Septencoracias morsensis described in 2016, and S. simillimus, which was named in 2024. It was found in the Fur Formation of Denmark, dating back to the Ypresian of the Lower Eocene Epoch, about 54 million years ago. Septencoracias is one of the earliest known members of Coraciiformes, lending insight into the earliest radiation of this group.

Palaeotodus is an extinct genus of todies in the family Todidae. The genus has at least three species known from fossils found in west-central Europe and western North America.

<i>Eocoracias</i> Extinct genus of birds

Eocoracias is an extinct genus of bird related to modern rollers and other Coraciiformes such as kingfishers, bee-eaters, motmots, and todies. It contains one species, Eocoracias brachyptera, and it lived approximately 47 million years ago based on dating of the fossil site. It is known for a specimen having preserved non-iridescent structural coloration on its feathers, previously unknown in fossil birds. Fossils have been found at the Messel Pit in Germany.
