There's a Goldcrest in the garage

This Goldcrest (Regulus regulus) was spotted in the garage last week, trying to leave by flying though the glass and not by the door at either end. It was soon caught and sent on its way. A common breeding bird in these parts we sometimes spot them in the garden searching shrubs, door and window frames for the small invertebrates on which they depend. At their size and relatively large surface area they have to catch prodigious quantitites of small inverrberates just to survive the day. The smallest European bird, averaging around 6 g—less than a two-pence piece—their weight depends on the time of day and the temperature. They lay down fat during the day and then burn if off at night to maintain their body temperature. Unlike some other small birds, they do not, when adequately fed, allow their temperature to fall during the night.
