Tricolored Heron (Egretta tricolor)

The Tricolored Heron (Egretta tricolor) formerly known in North America as the Louisiana Heron, is a small heron. It is a resident breeder from the Gulf states of the USA and northern Mexico south through Central America and theCaribbean to central Brazil and Peru. There is some post-breeding dispersal to well north of the nesting range.

Tricolored Heron’s breeding habitat is sub-tropical swamps. It nests in colonies, often with other herons, usually on platforms of sticks in trees or shrubs. In each clutch, 3–7 eggs are typically laid.

This species measures from 56 to 76 cm (22 to 30 in) long, and has a wingspan of 96 cm (38 in). The slightly larger male heron weighs 415 g (14.6 oz) on average, while the female averages 334 g (11.8 oz). It is a medium-large, long-legged, long-necked heron with a long pointed yellowish or greyish bill with a black tip. The legs and feet are dark.

Adults have a blue-grey head, neck, back and upperwings, with a white line along the neck. The belly is white. In breeding plumage, they have long blue filamentous plumes on the head and neck, and buff ones on the back.

Tricolored Heron stalks its prey in shallow or deeper water, often running as it does so. It eats fish, crustaceans, reptiles, and insects.

Purplish-mantled Tanager (Iridosornis porphyrocephalus)

The Purplish-mantled Tanager (Iridosornis porphyrocephalus) is a species of bird in the Thraupidae family. It is found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. It is threatened by habitat loss.

Inhabiting mossy forest and second-growth woodland, the Purplish-mantled Tanager is a fairly social species that can be found in pairs, mixed species flocks, or individually. With its rich purplish-blue back and contrasting yellow throat, this species is unlikely to be confused with any other tanagers within its range. Traveling individually, in pairs, or small family groups, this species forages mainly on insects; however, there have been observations of these species eating berries as well. Due to this species’ small range, unknown population status, and threats of habitat loss and conversion for cattle-grazing, the Purplish-mantled Tanager has been listed as near threatened on IUCN’s Watchlist.
