Spring-We Welcome Your Warm Embrace

It seems like it has been forever since we have seen a warm day.  'Warm' is relative though isn't it?  I was thrilled when the thermometer hit 42 degrees this morning and threw open the windows.  With temperatures forecasted to be rising to 64 degrees by next Thursday, I am preparing to deploy my mason bee tubes.  I have been cutting and rolling tubes for weeks now. 
It's also a fun project for kids to do.  I have 40 mason bee cocoons in the refrigerator that are 2/3rd through their food supply, so I'll be monitoring the weather very closely and checking out the wild plum and cherry trees to watch for signs of blooming.
On our way to 60 degrees today, I'm headed out to prepare both the mason bee housing and my purple martin housing.  Last year, my purple martins arrived on March 10th, and with warmer days now in the forecast, it's time to pull on my mud boots, trudge through all the mud and muck left by the melting snow & ice and put up their housing. 
For now, a few quick pictures!

Materials: Ruler, regular #2 pencil, scissors, tape, parchment paper (I also have a roll of unbleached parchment paper, not shown in this picture).  The pencil is the exact diameter for the mason bee holes.

My holding can.  Arranging different lengths of tubes together presents a 3D effect is supposed help the mason bee more easily find her home.
