i watched one...she went, i swear i could see that BIG dot and i was focused on it, i saw it for at least 100m.
also, sparows are cleaning in front of my hives, so...good luck with finding the dead ones, and there are hedgehogs, ants... a whole bee-related ecosystem.
take the time, sit in front of the hive (by the side) and watch, apitherapy plus learning
