Went down to the salini salt pans for a quick walk around. There were very few birds around but on my way back to the car I spotted the wasps' hive under a tree stump. I moved close as much as I dared but not too much.
T'hose are 'Baghal taz-zunzan' and a dangerous species of wasps. I was stung by one last Summer and had to go to the doctor's for a check-up - luckily he only prescribed some onitment. They have lovely yellow stripes, though and you have taken a great shot here. By the way, I saw an advert on fb to report sightings of their hives.
