Turquoise-winged Parrotlet
Forpus spengeli
Tiny parrot with green body, short pointed tail, and pale bill. Males have blue wings and cerulean rump; females are all green. Highly gregarious. Found in light woodlands, forest edges, second growth, open habitats, and urban parks, but typically avoids dense forests. Limited range in northern Colombia.
识别特征
Turquoise-winged parrotlets are typically 12 centimetres (4.7 in) long and weigh about 28 grams (0.99 oz). Their bodies are mostly yellow-green; eyes are dark brown and legs and beak are light peach. Turquoise-winged parrotlets are sexually dimorphic: males have bright turquoise feathers on their lower backs and rumps, and have purple-blue underwing coverts and axillaries. Females have no blue markings, but their foreheads and faces are brighter yellow-green than males'. Like all parrots, turquoise-winged parrotlets exhibit zygodactyly: two toes face forward and two toes face backward.
分类信息
Until recently, the turquoise-winged parrotlet was considered a subspecies of the cobalt-rumped parrotlet as Forpus xanthopterygius spengeli. However, in 2015 Bocalini and Silveira studied morphological differences between subspecies of cobalt-rumped parrotlets and determined that the turquoise-winged parrotlet was its own species, F. spengeli. This split was supported by Donegan et al. in 2016. There is continuing debate over the validity of this change. Some taxonomic authorities (including the American Ornithological Society) do not recognize this change in classification.

Blue Petrel
Halobaena caerulea
Rather small, attractively patterned petrel of cold subantarctic waters; not seen from mainland. Sometimes accompanies ships, especially near breeding islands and with groups of similar-sized and superficially similar prions. Blue Petrel told from all prion species by dark cap, half collar, and bold white tail tip. Also note differences in flight pattern; often a bit stronger and banks higher in strong winds.
Javan Kingfisher
Halcyon cyanoventris
Large kingfisher with a massive lipstick-red bill. Note dark head, dark chestnut throat and chest, purplish body, electric blue wings, and large black shoulder patch. Bright white wing patches revealed in flight. Uses a variety of both wet and dry lowland and foothill habitats, including ponds, mangroves, agricultural fields, open forest, and scrub. Can be close to human habitation. Gives high piping screams, often in series.
Black-chested Fruiteater
Pipreola lubomirskii
Scarce fruiteater found in cloud forest along the east slope of the Andes in Ecuador, southern Colombia, and northern Peru. Male has a solid black hood that is not bordered by yellow on the neck. Female is mostly green with yellow streaking on her belly. Yellow eyes and dark legs are also useful features in both sexes to separate them from similar species. Feeds on berries at middle to upper levels in the forest. Gives very high-pitched whistles, some very short and others long and drawn out.
