Useful to know

Euler's flycatcher is a small tyrant flycatcher often identified more reliably by voice than by looks, as its plumage resembles several other small flycatchers. It is widespread across mainland South America and occurs on Trinidad, but has been extirpated from Grenada. The species honors the Swiss-Brazilian naturalist Carl Euler, who worked extensively in Brazil. It typically forages quietly in the forest understory, making brief sallies to snatch insects.

Eurasian bittern

The Eurasian bittern or great bittern is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects.

Eurasian blackcap

The Eurasian blackcap is a bird usually known simply as the blackcap. It is a common and widespread typical warbler. It has mainly olive-grey upperparts and pale grey underparts, and differences across the five subspecies are small. Both sexes have a neat coloured cap to the head, black in the male and reddish-brown in the female. The male's typical song is a rich musical warbling, often ending in a loud high-pitched crescendo, but a simpler song is given in some isolated areas, such as valleys in the Alps. The blackcap's closest relative is the garden warbler, which looks quite different but has a similar song.

Eurasian chaffinch

The Eurasian chaffinch, common chaffinch, or simply the chaffinch is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate.
