How to recognize the blackbird

The blackbird is very easy to recognize by its deep black plumage, which clearly distinguishes it from other native birds. Only the bright yellow beak and the matching eyelid rings, which are created by an unfeathered area around the eye, add small splashes of color to their appearance. An untrained eye could see the blackbird at most with the star confused, which has a similar shape and coloration. But at second glance it stands out star characterized by its white pearl pattern and the blue-green iridescence of its plumage.

However, all this only applies to the male blackbirds - the females are much more simply colored. For a more detailed description, see the "How do male and female blackbirds differ?" section below.

How does the song of the blackbird sound?

The song of the blackbird consists of very clear and loud tones that form a melodic stanza. The males usually sit quite exposed and sing from a high vantage point.

How do male and female blackbirds differ?

The female blackbirds look very similar to their young and are just as inconspicuous. They have the same brownish plumage and a slightly lighter chest with dark streaks. The yellow of the beak and eyelid ring is slightly more pronounced than that of young blackbirds, but not as intense as that of males.

What does the perfect habitat for blackbirds look like?

Blackbirds originally settled in dense forests with a lot of undergrowth. Due to the increasing decline in this natural habitat, they also inhabit much more open areas today. They have proven to be quite adaptable, populating parks, gardens and even large cities in large numbers.

When is the breeding season of blackbirds?

The breeding season of blackbirds extends from March to July. During this time up to five broods can be possible. The incubation period for a clutch is about 14 days; then the hatched young are fed for another two weeks in the nest. The young blackbirds then fly out, but remain dependent on the care of their parents for another 14 days before they are on their own.

Where do blackbirds spend the winter?

Blackbirds are considered partial migrants in Europe. This means that only some populations leave their breeding range in winter, while others do not. The decisive factor is how severe the winters are in the respective areas. While our blackbirds usually spend the whole year in Germany, their conspecifics from northern Europe move south more often and are then sometimes our guests.
