Help the Friend's of Scadbury Park monitor changes in butterfly population. Learn how to identify different species and how to conduct a butterfly survey.

Swifts spend most of their lives on the wing, only landing to nest and raise young. They arrive in the UK in May to breed, nesting high on buildings, often under the eaves, leaving in August to return to southern Africa. The number arriving in the UK declined by 47% 1995-2014. In Bromley numbers recorded are now very low. Reasons for the decline include loss of nest sites, less insect food & changing climate. Listen for their screaming cries and look for their crescent shapes as they fly high above us, often in groups, feeding on flying insects and spiders. If they are flying at roof level they may be looking for nest sites. Please let us know if you see any & if they are nesting near you.
