April 27, 2020 Some of my bees are smart

Some of my bees are smart and some are really confused.  I like the ones
who quickly decide which tube to use.  Others fool around for up to 10 minutes before finally
deciding which tube to us.  Some bees are so stupid that they try to force their
way into a tube which is clearly to small.

On condo#1 the bees basically avoid the tubes in the middle of the house.
On condo#2 a one tube in the middle has been used.

url in the INFORMATION  page confirms my observation that mason bees like to "hang together".

I usually see two or three return to the condo at the same time.
