What do moorhens look like?

Moorhens have blue-black plumage overall. The back and upperwings have a dark brown wash and there is a white stripe on the flanks and white lateral undertail coverts.

On the head the bill is red with a yellow tip which extends upwards to cover the forehead with a red frontal plate. The eyes are dark red, the upper legs are bright orange, and the lower legs and feet are bright greenish-yellow.

Male and female moorhens are similar, although the male is slightly larger than the female.

Juveniles are browner with a paler belly and throat. The streaks on the flanks are dull white, and the bill and legs are dark.

How do moorhens breed?

Moorhens breed between the middle of March and the middle of May, sometimes in small colonies, and produce 3 or 4 broods a season. They are monogamous and form pair bonds. They situate their nests in shallow water anchored with vegetation, or on the ground in a low shrub, or on floating vegetation. Both male and female build the nest which is a wide, shallow cup made from dead plant matter, twigs, coarse stems, and lined with softer grass and leaves.

Moorhens lay up to 6-10 smooth, glossy, greyish-white eggs with reddish-brown or olive markings, which are incubated by both parents for 18-21 days. Chicks are precocial and covered in black down. The bill is red with a black tip. They are fed by both parents but leave the nest at about 2-3 days when they can feed themselves. They fledge about 42-49 days after hatching and reach sexual maturity at 1 year.

Young moorhens from the early broods will help their parents raise subsequent broods.

What do moorhens eat?

Moorhens are omnivorous. They eat berries, seeds, grasses, roots, and aquatic plants which they forage by diving. They will also take snails, worms, crustaceans, grasshoppers, insects, algae, tadpoles which it picks from the surface of the water or by dabbling.

Occasionally they will eat other birds’ eggs.
