3 p.m. this afternoon I was out in the garden, when alerted by a high pitched strident call, heard only Sunday on the GBC Portland trip. Ran inside to get my bins and was soon on to a Yellow-browed Warbler feeding with Chiffchaff in the trees that overhang the old railway line which is now a public path. Didn’t appear to stay long – I lost it in the canopy fairly quickly although the Chiffie was still around 30 mins later.
