Common Nightingale Luscinia megarhynchos

Common Nightingale Luscinia megarhynchos is a migratory inconspicuous songbird of rusty brown colour. In our country it is a synonym for beautiful singing. We can hear nightingales sing mostly in warm bushy forests of lower parts of the Czech Republic from the second half of April until July. It has unusually rich vocals, including flute tones, strong beat, whistling and chirrup. Nightingales were often caught and kept in cages in the past. Their nests are usually built on the ground in dense bushes. Only female nightingales sit on eggs and take turns with males in caring for the young. Their food is almost exclusively animal, only in autumn they feed on berries. In shrubby vegetation near the Olza river, there are more than ten nesting pairs of this endangered, by law protected species.
