I have shown stamps of this 2014 set before. Here is the last of it featuring a pair of Swinhoe's pheasants (Lophura swinhoei). The species has already been described.
Thank you Su Wu!
The stamp to the left depicts the horned lark (Eremophila alpestris). It is also known as shore lark and it can be found across the northern hemisphere. It has 42 subspecies. During the summer, males have two tufts of black feathers that look like horns, hence its name. It feeds on invertebrates and plant material. It is listed as of least concern though populations are declining.
The stamp to the left features a male and a female long-tailed meadowlark (Leistes loyca). In addition to Argentina, this species can be found in Chile and the Falkland Islands. It has four subspecies. It feeds primarily on insects with fruit playing a minor role in its diet. It is listed as least concern.
The stamp to the right depicts a pair of saffron-cowled blackbirds (Xanthopsar flavus). This endangered bird can be found in north-east Argentina, south Brazil, south Paraguay and Uruguay. It has no subspecies. It feeds mostly on insects and spiders and occationally on small vertebrates and seeds.
Issued in 2025, this bird stamp from Uruguay features the toco toucan (Ramphastos toco), the largest toucan species in the world. It is endemic to South America and it has two subspecies. It feeds on fleshy fruits, eggs, insects, small vertebrates and the nestlings of other birds. The toco toucan prefers semi-open habitats in contrast to other toucan species. The breeding season differs between regions. Finally, they are hunted by humans for their meat and for the pet trade.
The first stamp depicts the great spotted woodpecker (Dendrocopos major), which was presented already in a cover from Switzerland.
The second stamp shows a Eurasian wren (Troglodytes troglodytes). This migratory species is found in Europe, Asia and areas of northern Africa. It has 28 subspecies. It feeds on insects.
The second stamp shows a western yellow wagtail (Motacilla flava). It has ten subspecies. They breed in Europe and Asia while they winter in Africa and south Asia. They feed on insects.
Finally, the pictorial postmark shows a pair of Atlantic puffins (Fratercula arctica), which have been discussed in the past.
The first stamp depicts a male blue-winged kookaburra (Dacelo leachii). Males have blue tails while females have rufous ones. It has four subspecies. It feeds on insects, spiders and other arthropods, lizards, frogs, fish, earthworms, rodents and small birds.
The second stamp shows a sacred kingfisher (Todiramphus sanctus), which has been discussed in the past.
The second stamp was issued in 2009 and it depicts the California condor (Gymnogyps californianus), a species of vulture. It is listed as critically endangered. It has an impressive lifespan of up to 60 years. As other vulture species, it feeds on carrion.
The lower bird stamp, issued in 1991 too, shows the Palau fantail (Rhipidura lepida), which is also endemic to Palau. It feeds on insects.
