Individual study: A test of the use of artificial nest forms in common swift Apus apus nest boxes in southern England
Newell D. (2019) A test of the use of artificial nest forms in common swift Apus apus nest boxes in southern England. Conservation Evidence, 16, 24-26
Common swifts Apus apus have shown significant declines in the UK over recent decades, and one possible cause is loss of nesting sites. Nest boxes have previously shown to be effective for this species. Here we test whether the addition of an artificial ‘nest form’ affected the occupancy of nest boxes. Nest boxes that contained a form were 4.6 times more likely to be occupied by common swifts than nest boxes without a form. The design of the form did not appear to affect occupancy rate. Further study is needed to discover whether nest forms increase overall occupancy rates.
