Colour-ringed Whimbrels

Icelandic Whimbrels Numenius phaeopus islandicus are regular spring and autumn migrants in Ireland and many occur at North Bull Island. In spring, the majority of birds occur in the last week of April and the first week of May with smaller numbers during autumn passage in August and September. However, ringed birds could turn up at any time.

Researchers who are currently trying to unravel the migratory habits of this species and would appreciate reports of any colour-ringed birds observed.
