Friday sounds warmer, watching for some SY males !?
Offering pine straw, first time, instead of wheat, doubled pre-nest as recent cold front moved in & plugged vents!
No feedback on pre-nest, as nesting hasn't begun here.
Wood housing, has kept birds safe n comfortable so far.

Are you seeing many young Females yet?
Good Season your way
