Bumble bees in bird house

Kathy- Langley, BC sent me these photos of a bumble bees nesting in a bird house last spring. 

This is not an uncommon occurrance.  Bumble bees will nest in the ground, in a wall, in a bird house or other structure that will keep the weather out.  Bumble bees nest within insulation, grass or other similar materials.

Birds bring nesting materials like moss and grasses into their bird house and leave after their young have hatched. 

“When you see them up close they have an incredible amount of pollen on their back legs.  The opening into the bird  house is 1 1/4″ so you can see how huge they are.”

 
Underneath the moss is a bumble bee colony.  One bumble bee guard is walking on the surface of the colony.



This is a guard- watching out for predators.




Bumble bee on the left is cooling the colony with its wings.  The bumble bee on the right seems to be ready to go and gather more pollen and nectar for the young bees.




Coming in for landing.




Resting after a long flight.




Making room for a larger colony by removing excess moss material.
