Cassiobury Park - 8.4.13

A handful of Redwing were dotted around the park still and a couple of Siskin were heard around the yard including one that during it's song it mimicked a Fieldfare and Chiffchaff! I didn't know they could do that! 2 or 3 Chiffchaff were singing around the river and the male Mandarin was above the waterfall.
