A population of 20 house swifts in Discovery Bay, Lantau
I'd like to report that there are at least 3 bird nests built up outside the same highrise near my home in Discovery Bay, Lantau. I suppose the nests have been built for some time and they should be still active since a flock of 20 house swifts (I just identified them by naked eyes as house swifts, not likely to be pacific swifts) are being seen in recent time.
2 of the bird nests are built outside and under the bay window, above 20/F. The other one was built near the pipe at the roof of the building. The latter was not so sure since it's too high for me and I just haven't got a free time to observe them by a field scope.
I'll try to post some photos for the committee. Thanks.
