Thank you Gerdientje!

Both owl stamps belong to the same set ("Safari in the Netherlands - Owls"), which was released in 2024. Both species, the Eurasian eagle-owl (Bubo bubo) and the little owl (Athene noctua) have been presented in the past.

 

The first stamp was issued in 2024 and it shows a whooper swan (Cygnus cygnus), which we have seen before.

The second stamp was issued in 1963 and it depicts Lidth's jay (Garrulus lidthi). It is native to Japan. It feeds on plant material, invertebrates, small snakes and lizards. It is listed as vulnerable. 

Issued in 2014, the stamp depicts a spotted or Eurasian nutcracker (Nucifraga caryocatactes). The species has been discussed in the past.

Thank you Mark!

The first stamp was issued in 2025 and it shows a group of Indian runner ducks (Anas platyrynchos domesticus), a breed on the domestic duck. They were intianially bred in Indonesia before they became widespread in the western world. They have a variety of colours and a high egg production. They also cannot fly.

The next bird stamp, issued in 1996, depicts the migratory greater white-fronted goose (Anser albifrons). It can be found in Alaska, Canada, Greenland and Russia during breeding season but it flies south for the winter. It has five subspecies. It feeds on plant matter.

The final stamp was also issued in 2025 and it shows the northern pintail (Anas acuta), which has been presented in the past.

Issued in 2000, the first stamp shows an American kestrel (Falco sparverius). It can be found in North, Central and South America. The northern populations are migratory. It has 17 subspecies. The male, shown on the stamp, has blue-grey wings and a rufous tail with a single black band on its end. The female has rufous wings and tail with many parallel black bands across its length. It feeds on insects, small rodents, small birds and reptiles. It is used in falconry.

The final stamp, issued in 2012, depicts a peregrine falcon (Falco peregrinus). This species has been shown on a number of stamps already.

Issued in 2019, the first stamp depicts a falconry scene. More specifically a Eurasian goshawk (Astur gentilis) hunts a ring-necked pheasant (Phasianus colchicus). The Eurasia goshawk is widespead in Europe and Asia. Birds from northern regions are migratory. It has seven subspecies. It feeds on both birds and mammals.

The ring-necked pheasant has been presented in the past.

The second stamp, issued in 2005, shows a tawny owl (Strix aluco) which has also been shown before.

Issued in 2024, this stamp depicts the critically endangered Philippine eagle (Pithecophaga jefferyi). As obvious by its name, it is endemic to the Philippines and it is the country's national bird. It feeds on mammals, reptiles and birds.
 

Issued in 2003, the two bird stamps belong to the set "Arctic tundra". The middle stamp shows the gyrfalcon (Falco rusticolus), which can be found on the Arctic coasts and associated tundra. It is the largest species of falcon. It feeds on birds and small mammals. It is used in falconry.

The final stamp shows the northern raven (Corvus corax), for which I have written in the past.

The little bustard (Tetrax tetrax) can be found in southern Europe and central and western Asia. It is partly migratory. The breeding male has a blue-grey face and bands of black and white feathers on its neck while the non-breeding male and the female are brown coloured. It feeds on both plant material and terrestrial invertebrates. Due to habitat loss, it is near threatened.

The bluethroat (Luscinia svecica) is widespead across Europe and Asia. It can also be found in Alaska and the Yukon Territory. It is migratory. It has twelve subspecies. It can mimic the sound of other birds. The male, shown on the stamp, has a blue and read throat while the female has a white one. Finally, it feeds on insects and other invertebrates and plant material.

The stamps were issued in 2012.

 Thank you Vural!

The near threatened bearded vulture (Gypaetus barbatus) can be found in areas of southern Europe, Asia and Africa. It has two subspecies. It is a scavenger that feeds predominantly on bones and to a lesser extend on the flesh of carcasses.

The stamp was issued in 2025 in celebration of the 100 years of the Goldau Nature Reserve and Wildlife Park.

The cape parrot (Poicephalus robustus) is endemic to South Africa. In contrast to the male, the female has a red forehead. It is a vulnerable species and its trade in the pet market is illegal. It feeds on seeds, nuts, berries and nectar.

The hyacinth macaw (Anodorhynchus hyacinthinus) is another vulnerable species of parrot native to central and eastern South America. It is the largest macaw species. It feeds on nuts and fruit. It can be kept as a pet.

The sulphur-crested cockatoo (Cacatua galerita) can be found in northeastern Australia, New Guinea and some Indonesian islands. It has four subspecies. It feeds on fruit, seeds and buds. It can also be kept as a pet.

The stamps were issued in 2016.

The northern cardinal (Cardinalis cardinalis) can be found in central and eastern North America as well as portions of Central America. It has 18 subspecies. Females are of redish olive colour while males, shown on the stamp, are bright red. It feeds on seeds, fruit, insects and snails. It is the official state bird of seven states of the USA.

The blue jay (Cyanocitta cristata) is a species of corvid that can be found in central and eastern North America. Some populations are migratory. It has four subspecies. It is omnivorous feeding on seeds, nuts, fruit, insects and other invertebrates.

The evening grosbeak (Hesperiphona vespertina) is a vulnerable species found in North America. It is migratory and it has five subspecies. It eats seeds, berries, the sap of maple trees and insects.

This stamp set was issued in 2022 in celebration of Christmas.

Thank you Henriikka!

Steller's eider (Polysticta stelleri) is a migratory duck species found along the areas of the Arctic coast. It feeds on crustaceans, molluscs and other marine and freshwater invertebrates. As can be seen on the stamp issued in 2001, males (front) and females (back) have different coloured plumage with the latter being mostly brown and the former more colourful.

We have recently seen the snowy owl (Bubo scandiacus). Here it is on a stamp issued by Belarus in 2023.

 

Thank you Marina!

Issued in 1991, the stamp shows a little grebe (Tachybaptus ruficollis or Podiceps ruficollis). It has a wide distribution as it can be found in Europe, Africa and Asia. The populations in areas were the water freezes during the winter are migratory. It has ten subspecies. It feeds on insects, small fish, amphibians, molluscs and crustaceans.
