Weight: 5-6g/kg  /  Length: 12cm  /  Wingspan: ?
NO UK STATUS IUCN Red List: Least Concern

A Talamancan Montane Forest endemic with unresolved taxonomy - some consider the Grey-tailed Mountaingem of Southern Costa Rica to be a subspecies of the White-throated while other consider then to be a species in their own right. The male and female are very visually distinct with the the male having a bright white throat while the female has an orange throat and chest, and is extremely similar to females of certain other species in Lampornis. It is found from 1500m altitude and replaced at lower ones by the closely related purple-throated mountain-gem.

The smallest species of amazon parrot, it is also the only amazon species to be strongly sexually dimorphic enough for easy differentiation in the field with the males having red shoulders that the females lack. As with many parrot species they are long lived and have been recorded living 40 years in the wild and over 50 in captivity. Native to Central America, there are some feral populations in places like Puerto Rico and Texas.

A widely ranging species found from the Great Lakes to near the Southern edge of Brazil including across the Caribbean, although it mainly favours coastal sites  particularly mudflats and mangroves. The subspecies aren't clearly understood how they intergrade and this bird falls within the border range of three and thus hasn't been identified. They are specialists in feeding on crustaceans and the bill sizes of the different populations correleate to the prey species within that range.

NO UK STATUS IUCN Red List: Least Concern

A common resident of Caribbean and Central American Wetlands, the Northern Jacana is an unusual bird in several respects - while most initially the most obvious feature may be its huge splayed feet which allow it to spread its weight to walk on floating water plants easily. However, it also has spurs on its wings which can be used for defense. There is also the unusualy behaviour where an adult jacana can carry its clutch of chicks under its wings to escape safety, however the plethora of dangling ffet from a single bird does lend to an element of eldritch horror.

NO UK STATUS IUCN Red List: Vulnerable

The heaviest and most Northerly of the currasows, they primarily feed by taking windfall fruit from the forest floor. They are a monogamous species which can live over 20 years in the wild althoguh are slow to reproduce. They can have a somewhat aggressive temprament, even having been known to attack humans, in which instance they target the eyes. These birds I saw had moved into the environs of Rescarte Wildlife Rescue Centre, seemingly lured by the prospect of easy food, if somewhat baffled by their counterparts in cages.
