Common Tern -
Sterna hirundo
|
|
The results page for each species includes a summary of the first
arrivals and last departure localities and seasonal records by week.
In consultation with RBBP
any records of this species in
March to July are currently considered as confidential. Whilst
this errs on the side of caution, and may therefore hide some
passage records, it is aimed at preserving sensitive nesting sites.
