Bees Perched on Blades of Grass

Has anyone seen this?  I installed 3 packages of bees a month ago and after a couple days when it warmed up I noticed quite a number of bees that would fly out of the hive, land on the ground and then climb up an individual blade of Kan-tuck-ee bluegrass and just perch at the top.  Sometimes they would stay for quite awhile and then take off again.

I didn't think much of it and chalked it up to orientation but today my buddy noticed the same behavior in a package he had just hived.  Orientation you think?  Sick bees maybe? Didn't seem like they stayed on the ground as though they were on their last legs. 

I searched the forum a bit and didn't come across anything similar and my copy of Huber is in the shop.

I am stumped. I'll be checking back to see what the answer is.

Maybe it's cold so they need to perch on the grass to warm up a bit away from the ground?

That could be.  It was snowing when I hived them and warmed up a couple days later.

It's a mystery.  I guess that if we knew what they were doing all the time it wouldn't be as much fun.

Is it possible they are collecting water? I sometimes spray the grass in front of the hives and bees will collect water off the grass.
