I don't know what I saw!

Last week while dropping my mum off, I briefly saw two birds around the size of a thrush. They were on the ground pecking. One was stronger coloured than the other (they seemed to be together) a bit speckly with a black cap. I assumed it WAS a blackcap but looking at the ID books they're not speckly. I've been back a few times but haven't seen them again. Any ideas please? Also saw 5 or 6 birds just rootling around by the Madjeski stadium that looked like redwings but they had very auburn chests. Were they something else? Very pretty whatever they were. Thanks.
