Taxonomy:
Order Columbiformes
Family Columbidae
Range:
The red-billed pigeon is found from southern Texas, United States, and north-western Mexico south to Costa Rica.
Size:
This species is 33-36 cm long and has a wingspan of 58-61 cm. They weigh 230 g.
Habitat:
They are found in river woodlands and tall brush, namely undisturbed native woods, of hackberry, mesquite, huisache, ebony, and other trees. They are also found in dry woodlands of various types, generally avoiding more humid regions of rain forest. They are present from the lowlands up to an altitude of 2.100 m.

Common name:

Taxonomy:
Order Passeriformes
Family Columbidae

Range:
The eared dove is a resident breeder throughout South America from Colombia to southern Argentina and Chile, and on the offshore islands from the Grenadines southwards. It may be a relatively recent colonist of Tobago and Trinidad.

Size:
These birds are 22-25 cm long and weigh 100-120 g.

Habitat:
The eared dove is found in savannas, secondary growth scrubs and other open areas, including agricultural land. They readily adapt to human habitation, being seen on wires and telephone posts near towns and even in public spaces of large urban areas. These birds are present from sea level up to an altitude of 2.000 m.

Diet:
These granivores eat the seeds of a wide variety of wild plants, but also consume maize, wheat, rice, and soybeans which form the bulk of their diet in agricultural areas.

Breeding:
Eared doves can breed all year round, the exact breeding season varying between different parts of their range. They build a small stick nest several meters up in a tree, where the female lays 2 white eggs. The eggs are incubated for 12-14 days and the chicks fledge about 9 days after hatching.

Conservation:
IUCN status - LC (Least concern)
This species has an extremely large breeding range and, although the global population size has not been quantified, it is described as common. The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat, so this species is not threatened at present.

Common name:

Taxonomy:
Order Columbiformes
Family Columbidae

Range:
This species is endemic to the central and southern regions of Luzon and the smaller offshore island Polillo, in The Philippines.

Size:
The Luzon bleeding-heart is 30 cm long and has a wingspan of 38 cm. They weigh 180-190 g.

Habitat:
They are mostly found in primary and secondary forests from sea level up to an altitude of 1.400 m.

Diet:
They feed on seeds, fallen berries and a variety of insects and worms found on the forest floor.

Breeding:
These monogamous birds usually pair for life. They nest in May-August, building a cup-shaped nest out of twigs and other plant material. The is placed on bushes or creeping plants, not far from the ground. There the female lays 2 creamy white eggs which are incubated by both parents for 15-17 days. The chicks are fed crop-milk by both parents and fledge 10-14 days after hatching, but stay with their parents for up to 3 months.

Conservation:
IUCN status - NT (Near-Threatened)
This species has a restricted breeding range and, although the global population size has not been quantified, the species is described as usually rather scarce or rare. There are no data on population trends; however, the species is suspected to be declining at a moderate rate, owing to habitat degradation and hunting. These birds are trapped for meat and for sale in the pet trade and in recent years a lot of land was damaged with the eruption of Mt. Pinatubo. Logging is the main cause of habitat degradation for this species.

These birds breed in March-June. The female builds a flat, loose nest on the ground, in low bushes, or in the fork of lower tree branches. Nesting materials are provided by the male and consist mainly of twigs and pine needles. The female lays 1, rarely 2 eggs which are incubated by both parents for 18-20 days. The chicks fledge 28-30 days after hatching.

Conservation:
IUCN status - LC (Least concern)
This species has an extremely large breeding range and a global population estimated at 4 million individuals. This species was hunted to low numbers in the beginning of the 20th century, but since then recovered, following hunting regulations. The population is believed to be currently facing a very small decline, which is not sufficient to cause the species to be considered threatened.

Turtle dove

Streptopelia turtur

Photo by Roger Wyatt (Focusing on Wildlife)

Common name:

Taxonomy:
Order Columbiformes
Family Columbidae

Range:
The turtle dove breeds in most of Europe, with the main exceptions being Ireland and Scotland, Iceland, Scandinavia and northern Russia. They are also found breeding around the Mediterranean basin, throughout Turkey and the Caucasus and into the Middle East. They winter in Africa south of the Sahara, mostly in Senegal and Mali and other countries of the Sahel.

Size:
They are 25-27 cm long and have a wingspan of 49-55 cm. Both males and females weigh around 140 g.

Habitat:
They breed in open lowland deciduous woods and copses with rich undergrowth, mainly in agricultural areas but also in more open country with dense scrubs and isolated trees. They winter in dry scrubland and savanna.

Diet:
Turtle doves mostly eat the seeds of cereals and weeds. They also eat fruits and berries and may occasionally take insects and their larvae.

Breeding:
They breed in April-September. These birds mate for live, each year both male and female collaborate to build the nest, a simple platform made of twigs and roots, lined with softer materials such as grass and leaves. The nest is placed on tree or scrub, at an height of 2-3 m. The clutch consists of 1-2 white eggs which both parents incubate for 13-16 days. The chicks fledge after 20 days and become independent soon afterwards.

Conservation:
IUCN status - LC (Least concern)
With a global population of 20-100 million and an extremely large breeding range, the species is not considered threatened at present. Still, the turtle dove may have declined by as much as 67% in parts of its range, and the species is affected by habitat loss and unsustainable levels of hunting in southern Europe and northern Africa.
