We have had swallows nesting in the shed Southern spain?

Question

We have had swallows nesting in our shed we live southern spain they flew about 3 weeks ago but we have noticed they roost in the nest at night and sometimes during the day is this common

Answer 1

Most birds do not return to their nest once they leave..but swallows are an exception to this rule..yes they will often use the nest as a sleeping spot overnight or just a safe place to rest.

Answer 2

I always thought that swallows lived in the UK in summer and Africa in winter but then again Southern Spain is quite close to africa.  maybe the are illegal immigrants and sponging of the indiginous birds of southern spain.....hehehe
