I kept several of these birds in a cage for nearly a year, but they were too timid to be interesting in confinement. They could not bear any approach to them, without fluttering violently. They were very restless, walking rapidly about the cage-floor all day long, invariably walking over each other, rather than deviating from their course. Only one or two habitually perched. The Pea-dove has the habit of jerking the head by quickly shortening, and then lengthening the neck, immediately and invariably followed by a flirt upward of the tail; this action my captives were perpetually performing at intervals of a few seconds, when not walking. They slept on the floor of the cage, but were extremely wakeful. I have many times crept silently into the room at various hours of the night, taking off my shoes and moving with extreme caution, but always found them wide-awake; perhaps sensible of the light of the candle, even when the eyes were closed. My servant, however, found them asleep very early one morning, when they awoke with a start: the head was not behind the wing.
They were jealous of other birds, and, notwithstanding their gentle physiognomy, irritable and pugnacious. A Cashew bird that was a fellow-prisoner, they would strike at with the wing, and even if I myself suddenly approached, the wing was raised in defence. They were spiteful towards an unoffending Kildeer Plover, pecking at him so violently as to pull the feathers from his side, and make him cry out. I fed them with maize.
I have now in my possession a Pea-dove, shot by Sam in December, the lower mandible of which is distorted by the point being turned on one side, so that the mandibles cross as in the Cross-bill. The tips, however, could be brought into contact. It was shabby in plumage, and in very poor condition, the cause of which was obvious, for, open the plumage of the under parts wherever I would, the body was swarming with lice (Nirmus); and a large proportion of the body feathers were crowded with nits to such a degree, that on one feather which I placed under a lens I counted upwards of 170; and there were other feathers more crowded than this. I judged it to be a moderate estimate, that on this unfortunate bird there were not less than 500 lice, and 10,000 nits. On one of the thighs, where they were very thick, there was an ulcer. In addition to this, two large bird flies (Ornithomyia) flew from the plumage, while I was examining it.
The nest is, as usual, a loose platform of twigs interlaced, with scarcely any hollow, and no leaves; it is often built in an orange, or a pimento, and contains two eggs of a drab hue. Near the end of March we started a Pea-dove from the centre of a lofty Ebby palm (Elais) in Mount Edgecumbe; it immediately alighted on the ground just before my lad, and began to tumble about in a grotesque manner, affecting inability to fly. Sam was not to be caught, however; but calling my attention to the circumstance, we began to peer among the fronds of the tree, where we presently discerned the projecting ends of the twigs that constituted her nest, the centre of her fears and anxieties. It was inaccessible, however, when discovered.
GROUND DOVE.[90]
Chamæpelia passerina.
| Columba passerina, | Linn.—Aud. pl. 182. |
| Chamæpelia passerina, | Sw. |
[90] Length 6½ inches, expanse 10¼, flexure 3¼, tail 2⁷⁄₂₀, rictus ⁶⁄₁₀, tarsus ¹³⁄₂₀, middle toe ¹³⁄₂₀. Irides lake-pink; feet pale flesh colour; beak orange, black at the tip; eyelids yellow.
Though it would be scarcely proper to term this little bird gregarious, it is certainly social, being rarely seen alone. In pairs or small companies of three or four, it frequents pastures, on the short turf of which it runs with considerable speed; and is rather loath to take wing, often allowing a person to approach within a few yards. If one fly, however, all fly; but seldom go far; alighting either on the ground again, or on some neighbouring tree of small elevation. As it runs along, the tail is usually erected, which gives it the aspect of a miniature fowl.
