Spent last week in Bulgaria photographing winter birds. It was very cold there, but brighter than UK with some nice snowy scenes. Too much snow, however, for the main target of our visit. The Golden Eagle hides were inaccessible due to heavy snow the week before.
We had plenty feeder birds to photograph though - lovely Sombre Tits, Tree Sparrows, Greenfinches and you can never have too many Hawfinches (opposite).
We also spent a few days in a Goshawk hide way up a mountain, getting close encounters with a lovely female.
