Birds of Celebes; Cuculidae. 
The correspondence in habits between Eudynctmis and Cuculus is further 
displayed by the circumstance that the young Crows, which have the misfortune 
to find themselves in the same nest with the Eudynatnis, are sometimes ejected, 
“in-obably”, as Mr. Hume says, “by the young Cuckoo; I have found the latter 
in a nest with three young (i•ow^s, all freshly hatched, and a week later have 
found the young Crows “missing” and the young Cuckoo thriving”. Mr. Hume 
was of opinion that the Crow's’ eggs were not destroyed by the mother Cuckoo; 
Colonel Butler, on the other hand, says, ‘Vhen the hen birds lays she often 
turns some of the Crow’s eggs out of the nest, as I have several times examined 
Crowds’ nests and found three or four eggs one day, and on examining them a. 
day or two later have found some of the Crows’ eggs missing and Coels’ eggs 
in their place”. There is some reason to suppose that the Common Cuckoo, 
C. canorus, sometimes turns out one or more of the foster-parents eggs (Newton, 
Diet. 121). 
Capt. Hutton's observations on the old Cucidus mtermedius feeding a young 
one after leaving the nest have already been quoted from Hume’s gi-eat work; 
so, too, as has already been indicated, in the case of the present genus Hume 
has a similar observation : “I have never seen Crowds feeding fully fledged Coels 
out of the nest, whereas I have repeatedly watched adult female Coels feeding- 
young ones of their owm species” (Nests and Eggs 1891, 11, 393). There is, 
according to Prof. Newton, no evidence wmrthy of consideration that the female 
of C. canorus takes any interest “in the future w^elfare of the egg she has 
foisted upon her victim, or of its product”; the observations of Mr. Hume and 
Capt. Hutton, nevertheless, render it certain that two Cuckoos at least, and wm 
suspect all parasitic birds, are not totally devoid of sympathetic instincts for 
the wants of young members of their owm species; though, Avhether the indivi- 
duals observed looking after the young Cuckoos were their identical mothers or 
not, there it no evidence to show. 
70. EUDYNAMIS MINDANENSIS (L.). 
Philippine Koel. 
While the preceding species, E. tnelanorphyicha of Celebes and Sula, is 
readily distinguishable by its black bill from other members of the genus Eudp- 
naniis, the distinguishing characters of the remaining species, which are spread 
out from India and S. China across the Archipelago to New Guinea and Australia, 
are by no means so strongly pronounced. Especial care, too, is called tor in 
considering the w^estern forms, owing to the circumstance that -- in certain 
parts at least — the species are not perfectly stationary. Thus, the species 
spoken of as Eudpnamis macnlata by Swinhoe (P. Z. S. 1871, 394), David 
& Oustalet (Ois. Chine 60) and De La Touche (Ibis 1892, 480) is only a 
summer visitor to South China; and Mr. Whitehead remarks: “I never heard
