Common Cuckoo

Tentang

The Common Cuckoo is a medium-sized, brood-parasitic bird found across Eurasia and Africa. It is renowned for its distinctive 'cuck-oo' call and its unique reproductive strategy of laying eggs in the nests of other bird species.

105-130 g (male), 115-140 g (female)

Masa hidup

6-8 years (up to 12 years recorded)

Makanan

Insectivore, primarily caterpillars (especially hairy ones avoided by other birds)

Ciri fisik

Bulu

Adult males typically have slate-grey upperparts, head, and chest, with white underparts finely barred with black. Adult females can be similar to males (grey morph) or have rufous-brown upperparts and head, heavily barred with black (hepatic morph).

Bentuk paruh

Relatively slender, slightly downcurved, dark grey to black with a yellowish base to the lower mandible.

Warna mata

Bright yellow eye-ring and iris in adults.

Warna kaki

Short, strong, and yellow.

Ciri pembeda

Long, wedge-shaped tail, pointed wings, and a hawk-like silhouette in flight. The barred underparts are a key feature.

Penampilan muda

Juveniles are typically dark grey-brown on the upperparts, heavily barred with rufous and black, giving a scaly appearance. They have a white nape patch and a white-barred belly. The eye-ring and iris are duller, often brownish-yellow.

Perubahan musiman

No significant seasonal plumage changes in adults, though plumage can become worn by late summer. Juveniles molt into adult-like plumage in their first autumn/winter.

Dimorfisme seksual

Males are generally slightly larger and more uniformly grey. Females can be grey morph (similar to male but often with a rufous wash on the breast) or hepatic morph (distinctly rufous-brown and barred).

Cara identifikasi

1. 1

   Call

   The male's distinctive 'cuck-oo' call is the most reliable and often the first sign of its presence. Listen for the bubbling call of the female.

2. 2

   Flight Silhouette

   Observe its flight. It has a hawk-like silhouette with pointed wings and a long, wedge-shaped tail. It often flies with rapid wing beats followed by glides.

3. 3

   Plumage (Adult Male)

   Look for uniform slate-grey upperparts, head, and chest, contrasting with white underparts finely barred with black. Yellow eye-ring and legs are also key.

4. 4

   Plumage (Adult Female - Hepatic Morph)

   If you see a rufous-brown bird with heavy black barring on the upperparts and head, and barred underparts, it's likely a hepatic female cuckoo.

5. 5

   Plumage (Juvenile)

   Look for a scaly, dark grey-brown upperparts with rufous and black barring, a white nape patch, and barred underparts. Dull yellow eye-ring.

6. 6

   Behavior

   Cuckoos are often secretive, perching quietly in trees or shrubs. They are not typically seen feeding young, as they are brood parasites.

Habitat dan persebaran

Bioma

Forests, woodlands, scrublands, heathlands, grasslands, agricultural areas, and open country with scattered trees.

Persebaran geografis

Breeds across most of Europe and Asia, from the Atlantic to the Pacific. Winters in sub-Saharan Africa and parts of Southeast Asia.

Rentang ketinggian

Sea level up to 3,000 meters in some mountainous regions.

Lingkungan yang disukai

Prefers open or semi-open habitats with a mix of trees, shrubs, and open ground, often near water. The presence of suitable host species is a critical factor.

Perilaku

Waktu aktivitas

Diurnal.

Kebiasaan makan

Primarily insectivorous, specializing in large, hairy caterpillars (e.g., Lasiocampidae, Arctiidae) that are toxic or unpalatable to many other birds. They pluck caterpillars from foliage or the ground. Also consumes other insects like beetles, grasshoppers, and larvae.

Perilaku sosial

Solitary for most of its life, except during the breeding season when males establish territories and females seek out host nests. Not social outside of breeding interactions.

Pola terbang

Strong, direct, and hawk-like flight with rapid wing beats, often gliding. Can be mistaken for a small raptor, especially a Eurasian Sparrowhawk (Accipiter nisus).

Pola migrasi

Long-distance migratory. Breeds in temperate Eurasia and migrates south to wintering grounds in tropical Africa and Southeast Asia. Migration occurs mainly at night.

Teritorialitas

Males are highly territorial during the breeding season, defending their calling posts and display areas. Females are not territorial in the traditional sense but maintain a 'laying range' where they monitor host nests.

Reproduksi

Musim kawin

April to July in temperate breeding grounds.

Kebiasaan bersarang

Obligate brood parasite. Does not build its own nest. Females lay their eggs in the nests of over 100 different host species, though individual females often specialize in one or a few host species. Common hosts include Dunnock, Meadow Pipit, Reed Warbler, and Pied Wagtail.

Jumlah telur

A female cuckoo lays one egg per host nest, but can lay 12-25 eggs in a season across multiple host nests.

Deskripsi telur

Eggs are typically small for the cuckoo's size, often mimicking the size, color, and pattern of the host species' eggs. This mimicry is crucial for successful parasitism. Eggs can be white, blue, green, or spotted, depending on the host race.

Masa inkubasi

11-13 days, typically shorter than most host species, allowing the cuckoo chick to hatch first.

Masa terbang

17-21 days. The cuckoo chick usually ejects host eggs or young from the nest shortly after hatching, ensuring it receives all parental care.

Perawatan orang tua

None from the biological parents. The cuckoo chick is entirely raised by the unwitting host parents.

Tips lapangan

1. Listen for the call. The male's 'cuck-oo' call is the most reliable way to detect its presence, especially from April to July. Learn to distinguish it from other bird calls.
2. Scan for hawk-like birds. Due to its flight and silhouette, it can be mistaken for a small raptor. Pay attention to the lack of a hooked beak and prominent talons.
3. Look for host activity. While difficult, observing small passerines aggressively mobbing a cuckoo can indicate its presence, as they recognize it as a threat to their nests.
4. Be patient and observant. Cuckoos can be elusive. Find a good vantage point in suitable habitat and wait quietly, listening and scanning the trees and open areas.
