Common name:
green-throated carib (en); beija-flor-das-Caraíbas-de-garganta-verde (pt); colibri falle-vert (fr); colibrí caribeño gorgiverde (es); blaustern-Antillenkolibri (de)


Taxonomy:
Order Apodiformes
Family Trochilidae


Range:
This species is only found in the Caribbean, in the islands from eastern Puerto Rico and Grenada.


Size:
They are 10,5-12,5 cm long and weigh 5,5-8 g.


Habitat:
The green-throated carib is found in open secondary vegetation, semi-deciduous woodlands, rainforests, moist scrublands, agricultural areas and parks. It is present from sea level up to an altitude of 1.000 m.


Diet:
These birds mainly feed on the nectar of flowering scrubs and trees, including Heliconia, Lantana, Cordia, and Bryophyllum, as well as other flowering plants with long nectar repositories. They also eat flies, wasps, ants, small beetles and spiders.


Breeding:
Green-throated caribs breed in February-May. The female builds the nest alone, a compact cup made of bark and lichens, and lined with soft fibres of cacti, seeds, and tree ferns. The nest is usually placed in the fork of a twig, up to 9 m above the ground. There the female lays 2 white eggs, which she incubates alone for 17-19 days. The chicks are fed by the female and fledge 20-22 days after hatching, but only become fully independent 3-4 weeks later. Each pair raises 1, or rarely 2 broods per years.


Conservation:
IUCN status - LC (Least Concern)
This species as a small breeding range, but it is described as common. Global population trends have not been quantified, but the species is not believed to be declining and it is known to adapt well to human-affected habitats.

It is placed in low vegetation, 1-3 m above the ground, and often over water. The female lays 3-4 white eggs, which are incubated by both parents for 20-22 days. The chicks are fed by both parents and possible fledge 25-29 days after hatching.


Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is described as common. This population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Adelie penguin

Pygoscelis adeliae

Common name:
Adelie penguin (en); pinguim-de-Adélia (pt); manchot Adélie (fr); pingüino de Adelia (es); Adeliepinguin (de)


Taxonomy:
Order Sphenisciformes
Family Spheniscidae


Range:
This species is found on the coasts of Antarctica and in nearby islands such as the South Shetlands, the South Orkneys, Bouvet, Balleny and Peter Island.


Size:
These birds are 60-75 cm long and weigh 3,6-6 kg.


Habitat:
The Adelie penguin spends the winter in large coastal ice platforms, from which he dives in the sea in search of food. During the season they are found in beaches, rocky islands and other other areas free of ice.


Diet:
They catch their prey by pursuit diving, usually less than 20 m down. They mainly eat krill, but also fishes such as Myctophidae and the Antarctic silverfish Pleuragramma antarc
ticum, squids and amphipods.


Breeding:
Adelie penguins breed in October-February. They are monogamous and mate for life. The nest is a pile of stones on the ground, where the female lays 1-2 eggs. The eggs are incubated by both parents for 24-43 days. The chicks are fed by both parents and remain in the nest for 4 weeks, after which they join a creche of other juvenile while still receiving food from the parents. The chicks become independent about 2 months after joining the creche. Each pair raises a single clutch per season.


Conservation:
IUCN status - LC (Least concern)
This species has an extremely large breeding range and the global population is estimated at 4-5,2 million individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Coppery-chested jacamar

Galbula pastazae

Common name:
coppery-chested jacamar (en); ariramba-acobreada (pt); jacamar des Andes (fr); jacamará cobrizo (es); kupferglanzvogel (de)


Taxonomy:
Order Galbuliformes
Family Galbulidae


Range:
This species is found along the eastern slopes of the Andes, in southern Colombia, Ecuador and across the border into northern Peru.


Size:
These birds are 23-24 cm long and weigh 30-35 g.


Habitat:
The coppery-chested jacamar is found in mountain rainforests, especially along forest edges and in nearby second growths, at altitudes of 600-1.700 m.


Diet:
They eat a wide variety of flying insects, including beetles, wasps and butterflies, which they catch by sallying out from a perch and catching them in the air.


Breeding:
Coppery-chested jacamars nest in holes well-hidden in the ground. The female lays 1-4 white eggs which are incubated by both parents for 20-23 days. The chicks are fed by both parents and fledge 21-26 days after hatching.


Conservation:
IUCN status - VU (Vulnerable)
This species has a small and fragmented breeding range, and the global population is estimated at 2.500-10.000 individuals. The population is suspected to be declining slowly as a result of habitat destruction and fragmentation. The lower slopes of the eastern Andes in Ecuador are seriously affected by clearance for small-scale agriculture, and for tea and coffee plantations, with forest disappearing at an alarming rate. In Colombia, the forest remains as the climate and terrain are unsuited to coffee or tea growing. Proposals to build a new road in the area may represent a further threat.
