Hi Ecotrain Fam!
These bees are so thirsty they come every day to drink at this water barrel.
They drink for just a few seconds then move on giving over their place at the waters edge to the next, patiently waiting thirsty bee.
There is a post in the water for them to swim to and climb out if they fall in - which they sometimes do.
A wasp appears in there amongst the bees, all good.
