Northern Ireland’s first public CES bird ringing programme at Ecos Nature Park

Ecos Nature Park, Ballymena is the first public Constant Effort Site (CES) in Northern Ireland. The programme began on Monday 8 May 2017 and 11 more morning sessions will be spaced out across the summer. The bird ringing mornings are led by BTO licensed ringer and trainer Aidan Crean and will run from 8am to 12.30pm.

The Constant Effort Sites (CES) scheme is the first national standardised ringing programme within the BTO Ringing Scheme and has been running successfully since 1983.  Ringers operate the same mist nets in the same locations over the same time period at regular intervals through the breeding season at over 130 sites throughout Britain and Ireland. The results from the project provides valuable local site species knowledge plus builds a trend of information on abundance of adults and juveniles, productivity and also adult survival rates for 24 species of common songbird.

This programme is a great opportunity to see and appreciate all the small resident and migrant birds of Ecos Nature Park at close quarters and learn how and why we catch, ring and study wild birds.

Everyone is welcome along, there is no experience required.
