I believe there is a meat market not far from the threshold of one of the runways in BJL, which attracts a number of large birds and has resulted in a disproportionally high number of bird strikes, including the 2016 one which nearly wiped out both engines on a TCX A321. After that, Thomas Cook changed their flight times to depart BJL in the late evening once the market had closed - looking at the times of the TUI flights, it seems they’ve done the same.
Off topic but thought that pointless bit of trivia might be of interest.
