This, the largest of all our parasitic Cuckoos, has a rather curious breeding distribution. In the Himalayas it is a common bird from Kuman and Garhwal to the extreme East or Assam ; thence it extends throughout Burma, Malay States, Borneo, the Philippines and Celebes ; still further East it occurs in the Indo-Chinese countries, West and Southern China. South of the Himalayas it has been recorded from Chota Nagpore, also rarely from Madras City and Trichinopoly, while on the West it occurs not infrequently on the Malabar coast, Travancore, and is common in Ceylon. It breeds up to about 6,000 feet.
In the Western Himalayas the most common fosterer is Gramma¬toptila, and less often the egg is found in the nests of different species of Trochalopterum, while in the Eastern Himalayas most eggs are deposited in the nests of Garrulax moniliger and pectoralis. At odd times eggs may be found in the nests of almost any of the Laughing Thrushes, while still more rarely they have been taken from such unlikely nests as those of the Bulbuls and Quaker-Thrushes. In my own experience all such eggs have been deserted, but Fielden saw young Crested Cuckoos being fed by Quaker-Thrushes. Often many Cuckoos’ eggs are laid in the same fosterer’s nest, their appear¬ance showing that they are deposited by two or even three Cuckoos, so it is obvious that these birds do not have any special breeding territory.
In Assam most birds lay during May and June, but eggs may be found from early April up to the end of August ; in Burma April and May are the most popular months, while in Western India the last half of April to the first half of June.
The eggs of the Red-winged Cuckoo are just large editions of those of the Pied bird but perhaps more spherical and slightly paler on an average.
All the blue eggs of Cuckoos seem to take a dark stain from damp which I have never seen on any other egg and, though the spherical blue eggs of the Cuckoo are easy to distinguish from the longer and more pointed eggs of the Laughing-Thrushes, this stain sometimes helps to distinguish abnormally long eggs of the Cuckoo.
Fifty eggs average 26.9 x 22.8 mm. : maxima 29.9 x 22.9 and 26.9 x 24.4 mm. ; minima 25.4 x 21.7 and 26.3 x 20.3 mm.
