Very good blog from RSPB, do have a read. How does your garden do with this? Advertisements
Did you know … Swifts pair for life, meeting up each spring at the same nest site. The nest is located high up in the roof space under the eaves of old houses and churches where the birds are able to drop into the air from the nest entrance. The nest is built by both adults out of any material that can be gathered on the wing, including feathers, paper, straw, hay and seeds. It is cemented together with saliva, and renovated and reused year after year.
