燕巢雀佔? Nest Adoption?

燕巢雀佔? Nest Adoption?

麻雀會不會佔用雨燕巢呢?
Will Tree Sparrow use a Swift nest, or was it just curious?

That's a Red-rumped Swallow nest. Was this in Hong Kong? They are quite rare as breeding species here.
The sparrow was probably investigating potential nest sites. I think it's possible that it would take over a swallow nest if it thought it was suitable.

I saw in the photo description 嘉義 (Chiayi), which is a city in central Taiwan.

In Hong Kong, both Tree Sparrow and Crested Myna will use House Swift nest.
And House swift will use Barn Swallow nest.
在香港,麻雀及八哥均會佔用小白腰雨燕的巢。
而小白腰雨燕則會佔用家燕的巢。
