Heiistock's stock. Mr. Henstock lias bred this cross freely and lie presented 
jiie with the pair, which have been figured and described in Vol. VII. of 
this Magazine. Kxcept for the above iiientioned differences they are similar. 
It would be of much interest to note to what extent it differs after the 
second moult. — P^D.] 
Another iiileresliiig fact is that Nicobak Pigeons {Calcenas 
nicobarica) do not get full adtilt pluinage till they are four years 
old, at least that is the case with the 011I3' yomig one reared in 
these aviaries four years ago ; it is only now getting its white tail 
and adult plumage. I bought the parents in 1900 from Jamrach 
for £\\ they were then in perfect and full adult pltimage. They 
made tlieir first nest in 1904 and reared the aforementioned 
young one — the clutch consists of a single egg. The}' have 
several nests each season and young have been hatched out at 
different times, but excepting the above all have died before 
being fully fledged. Up till this stiinmer (1908) its plumage was 
a beautiful copper colour with very little green, and a black tail ; 
now it is becoming green like its parents and has almost got the 
full white tail. The old pair have not nested at all this season. 
I have now in my three aviaries, mixed series of: Pectoral 
and Zebra Finches, Canaries, Virginian Nightingales, Cockateels, 
Black-headed Nuns, Masked and Gouldian Finches ; Waxbills in 
variety. Spice Birds, Cutthroats, Avadavats, Firefinches, Manni- 
kins in variety, Ruficaudas, Bengalese, Bichenos, Nonpareil, 
Bulbul, Dominican and Green Cardinals ; Red-headed Finches, 
Weavers in variety ; Yellow-shouldered and Paradise Whydahs ; 
Glossy Starlings ; Pekiu Robins ; Budgerigars, and various Doves 
— 152 l>irds in all. They fly about outside every day, but at night 
when the lamp is lighted they go into their respective houses and 
the doors are shut, but the windows are all left open about six 
inches, so that they are able to fly out of doors as soon as it is 
light. 
Out in the Park are Rheas, F'lamingoes ; Sarus, Demoiselle 
and Crowned Cranes ; wild African and Barred Geese ; Ruddy 
and Common Sheldrakes; Whistling Tree Ducks; Gargane}', 
Mandarin and other ducks, and various kinds of pigeons. The 
Rheas, Flamingoes and Cranes are driven in at night; they are 
all very tame and come when called to be fed. 
One of my very interesting birds is a White Egret, very
