Regularly at nightfall, during the summer, I used to see many parties of Tinklings fly over Bluefields, with the usual vociferation, and wend their way to a spreading cotton-tree near the seaside, where, I was informed, they slept; whence, as regularly one might see them, in the early morning, emerging and dispersing to their places of diurnal occupation. One evening I went down to watch their arrival and proceedings. About half-an-hour before sunset, they began to arrive in straggling parties, but did not proceed at once to their roosting place, but congregated in a clump of smaller trees, about one hundred and fifty yards from it, on the banks of Bluefields River, where they clamoured in all sorts of metallic tones with unceasing vociferation. Some parties from a distance, coming straight to the roost, suddenly altered their course, attracted by the calls of these intermediate settlers, and joined them, and some even returned to them, which had already passed the spot. A few, however, went on to their destination, and when once some were there, their numbers soon increased, for the calling now proceeded from both quarters. As the parties arrived, one or two single birds kept flying from one station to the other, backwards and forwards. At length the whole assembled number on the intermediate station rose as by common consent, and flew in an immense flock to the number of nearly two hundred, to the roosting place, darkening the air, and making a loud rushing with their united wings. Others went on to arrive, until between four and five hundred, (I could not count very accurately) had assembled. Long before this, however, I had found that the real roosting place was not the large cotton-tree, that this was but another station of congregation, for as the evening advanced, they began to leave this, and to perch on the fronds of four or five cocoa-nut palms that were growing in two lines, of which the cotton-tree was the angle. The nearest trees to this point were first chosen, and few chose the second, till the first was pretty well crowded, nor the third till the second was occupied, and finally the numbers on each cocoa-nut were in proportion to its proximity to the central point.
