Yet another Yellow-browed Warbler passes through and calling Cetti's Warbler

Heysham Obs
Jean Roberts located a calling YBW along the north end of the reserve at about 0815hrs and it appeared to move inland along northern edge and was located in the large sycamore about an hour later (unringed as expected)

Another landmark, where we never thought we would get anywhere near last year's record catch, was our 200th Chiffchaff of the year - the vast majority in the last month or so and all but the odd one or two in rapid transit, based on retrap data and field sightings of unringed birds  - rather like the Yellow browed Warblers

Interesting to compare the fortunes of Willow Warbler and Chiffchaff over the years:
1986     Willow Warbler   440 (mainly due to tremendous spring passage during the Chernobyl weather) (grand total 1980-6 = 1425)
              Chiffchaff  33   (grand total 1980-6 = 85)

1996       Willow Warbler  260  (grand total 1980-1996 = 3459)
               Chiffchaff   35 (grand total 1980-1996 = 440)

2006       Willow Warbler  83 (grand total 1980-2006 = 4927)
               Chiffchaff     45  (grand total 1980-2006 = 870)

2014       Willow Warbler   180 (grand total 1980-2014 = 6144)
               Chiffchaff            227 (grand total 1980-2014 =  1648)

2015       Willow Warbler   125 (grand total 1980-2015 = 6269)   
(to date)  Chiffchaff            202 (grand total 1980-2015 = 1850)
