I'm new to the world of beekeeping - so today I noticed quite a few bees hanging out on the landing board of the SBB. The weather is quite warm (low 90's and humid). While I understand the bees congregating outside, I noticed quite a few are fanning-but the vast majority seem to be cleaning the SBB landing area by "sweeping" with their front legs and their heads are down. Just wondering if they are collecting dropped pollen or propolis or if they are just bored and very tidy? This is my first post to the forum and I am looking forward to all the info to be found here!
