But we caught a few birds around the farm orchard.
'Fascinating' fact: Both adult and juvenile House Sparrows do a complete moult after the breeding season (though obviously not all at once - that would be silly). So once that's complete you can't tell how old they are. But you can tell whether they're male or female.

'Fascinating' fact: You can tell how old Coal Tits are at this time of year (though I forgot to photograph the relevant bit). Young birds don't moult all of their greater coverts, so if you look carefully you can see difference in colour between the old ones and the new ones.
