Re: Another great day AND SCREECH OWL BOX

Kim, great question !!
my heavily biased vote is in favor of a native resident bird sp (WESO) vs. an introduced mammal sp (our local squirrel?  sorry I haven’t fully researched this and it’s a word-of-mouth thing that they’re introduced here in T Valley), so I’d kick those squirrels out even if it requires manually doing so several times   😉
I seriously hope nobody ever ever ever introduces squirrels into the South Hills or we might lose our state’s only endemic bird Cassia Crossbill ??  or at least put them at risk ?

Breeding Range

Nonbreeding Range

Historical Changes to the Distribution

Lodgepole Pine was projected to be much scarcer in the region 7,000–5,000 years ago, and the Cassia Crossbill likely evolved subsequently (20).

Re: Another great day AND SCREECH OWL BOX

Right? That’s what I said!  Yay, Tom and all those able to get the vaccine.  

If I may change the subject – I have a screech owl situation.  We’ve had families of WSOW nesting in our backyard owl box for the last 7 years.  Really cool!  Last year the mom, (I really think she’s been the same one) passed away.  😢 (another piece of lame ’20)  Dad, (not the first) raised the chicks and everything was mostly fine for the rest of the summer.  (Besides the lame Coopers Hawk)
THIS year – I have a squirrel nesting.  My question is … will a new pair kick the squirrel out or do I need to?  I’ve been hearing one out at night so it’s possible a there might be a new family, but how brave are they? 
Thanks so much for your thoughts – happy birds and happy vaccines.
