Evening nature

A few evenings ago, we happened to notice a lot of what appeared to be large insects - bee size or bigger - flying around over our back lawn, clearly caught in the setting sun from the west facing back window of our extension. Perhaps they were moths.

Then this evening, at around 2030, when it was nearly dark, a lot of what appeared to be bats. Bats of about the size and (in the dark) something like swallows or swifts in appearance, but flying in rather shorter lines. And we have never had either swallows or swifts in our garden before - although, to be fair, I did see some quite recently in Worcester Park and some more in Nonsuch Park, neither very far away. See, for example, reference 1.

On balance, I settle for the bats of today making a meal of the moths of yesterday.

Perhaps I need one of those bat detectors. Maybe the Epsom branch of Maplins does them.

PS: bats present again this Saturday evening, at about the same time. More bat-like on this occasion in that I thought I glimpsed their distinctive wing shape, not like that of a swallow or swift at all. On the other hand, it might just be a spot of the sort of image enhancement noticed at reference 2.
