You see the odd bumble bee here in area of Bruce County.........and the odd honey bee as well and some wasps but......
My tulip tree just bloomed this past week and a half and still blooming
there are thousand flowers on the 80 foot tree and that many pollinators or more.........I have never seen this many bees in my life..............a lot are bumble and a lot of them are honey bees...........
at night time the moths come
just wander how bees know how to do this and second of all.......where do they all come from....

no local hives that I know of around here.......this tree is in the middle of a small town......

It is possible your tulip tree has the best quality of food available to the pollinators.

I don't know about the other pollinators but honey bees seem to visit some plants one season and ignore them the next Lavender, sunflowers redbud, dandelion and crocus. Those plants are visited every year by our bees. There are others they visit every season but those come to mind off the top of my head.
Honey bees will travel a three mile radius from there hive to forage. They select the best quality they can find.

Thanks Margaret..

I know the tulip tree has tons of flowers and is full of nectar..........
the trees produce honey as well..........
I know the hummingbirds have been around too but nothing like the bees..........honey bees and bumble bees but mostly the honey bees I would say
shocked to see this many bees to be honest........

I had a lady here from the conservation authority since they are trying to make this a heritage tree...........and she was surprised at all the bee activity at the time........
most of the flowers are on the canopy but some are lower..........
all she said is a very healthy bee population.......... and that is a good thing likely
