JBX573 Chiffchaff
Ringed 29/08/2015 Billinge Hill, Merseyside.
Controlled 08/05/2016 Lista Fyr, Farsund, Vest-Agder, Norway. 773 km NE, 253 days.
It should be remembered that the line on the recovery maps simply joins the ringing and finding places and does not represent the route taken by the bird.
A check of the BTO Online Ringing Report (link here) for 2015 revealed there had only been a total of 7 BTO ringed Chiffchaffs found in Norway (includes all records received up to the end of April this year) although a total 26 Norwegian ringed birds have been found here. This shows that recoveries in Norway are particularly uncommon and this bird is potentially only the 8th British ringed Chiffchaff to be found there.

Ringed 17/09/2016 Billinge Hill, Merseyside.

days.The recovery of JBX773 fits in with the more usual pattern of recoveries for birds returning to the general area they came from. In fact this bird may have returned to the site or close to the site where it was originally bred. Many warblers disperse in random directions before migrating south in the autumn and this bird could have moved east to Billinge, where it was ringed, as part of its post juvenile dispersal last autumn.
256 first-year Chiffchaffs were ringed at Billinge last autumn. Peak migration was in September when 122 were ringed, including the bird in this photograph. |
