Agami Heron

The Agami Heron, Agamia agami, also known as the Chestnut-bellied Heron, is a medium-sized heron adorned with a unique coloration pattern that has earned it the nickname 'Hummingbird Heron' in Brazil. This species is the sole representative of its genus, Agamia, and is recognized by its short legs, elongated thin bill, and striking plumage. Adults boast a chestnut neck and underparts, complemented by a white line down the foreneck. Their wings shimmer with a green iridescence, while pale blue feathers grace the crown, sides of the foreneck, and lower back. The legs, bill, and facial patch are typically dull yellow, turning reddish during the breeding season.

Identification Tips

To identify the Agami Heron, look for its chestnut underparts and the distinctive white line down the center of the foreneck. The green gloss on the wings and the wispy pale blue feathers are also key features. Juveniles differ with their brown upperparts, white foreneck, and streaked brown-and-white underparts. The species' bill is notably longer than its head, aiding in identification.

Habitat

The Agami Heron favors swamp forests, mangroves, forest streams, and freshwater wetlands. It thrives in shaded environments, often hidden by overhanging vegetation.

Distribution

This Neotropical bird is found from Central America down to Peru and Brazil. Its range includes Mexico, Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, French Guiana, Suriname, Guyana, Venezuela, Peru, Bolivia, and Brazil.

Behaviour

The Agami Heron is a reclusive bird, seldom seen due to its preference for dense vegetation. It is generally quiet, but can produce snoring or rattling sounds, especially when disturbed. It stalks its prey in shallow waters, often remaining motionless or moving with deliberate slowness.

Song & Calls

This species is not known for a prominent song but may emit various snoring or rattling sounds within pairs or family groups.

Breeding

During the breeding season, both sexes exhibit courtship behaviors and may develop a silver crest. The lores can intensify to a vivid red color. They typically nest in colonies, constructing platforms of sticks in bushes and trees over water.

Similar Species

There are no similar species within its range that would be easily confused with the Agami Heron due to its distinctive coloration and habitat preferences.

Diet and Feeding

The Agami Heron's diet primarily consists of characins, small surface-swimming fish, along with occasional cichlids. It may also consume frogs, small reptiles, and snails.

Conservation status

The Agami Heron is currently listed as Vulnerable by the IUCN. Its discreet nature and the challenge of studying it in its remote habitat contribute to its perceived rarity. Conservation efforts are focused on protecting colony sites and gaining a better understanding of the species' range and habitat requirements.
