A bird in the hand is worth two in the bush. In Dutch the same expression would say "one bird in the hand is worth more than ten in the sky". This is very true at an airport. Every horizontal fixture and building at the airport is covered with spikes to avoid that birds use it as a comfortable seat with a view, but this bold little guy found the perfect spot after all. In spite of the huge efforts of our Bird Control Unit, there will always be an occasional crow to come laugh at us. Or is it a blackbird ? We humbly confess that we have become better at identifying Tupolev's and Airbuses than sparrows and finches.
