On the landfill site there were hundreds of gulls. Around the lake were: Teals, Herons, Lapwing, Coot, Tufted duck and Black-headed Gull. Along the paths were Chiffchaff, long-tailed Tit, Blue and Great Tits, Robins, Magpies, Jays, Carrion Crows, Jackdaws, Sparrowhawks, and a Peregrine Falcon! And the number of Tree Sparrows I saw was a big fat zero! 500-1 chance of seeing one, but no luck.
Despite the lack of Tree Sparrows it was an enjoyable walk.
