Small cloud of PM arrived over our site around mid day, circling n singing.
My partner called to describe the Happy commotion & was so taken up, didn't
think to grab camera, till birds started descending onto housing. Before
Commotion setteled, 2 additional ASY-M & 1 SY-f were Swooping between
Systems, checking cubys. A Lot O circling n chattering took place before all
Settled in to Roost, just before dusk!

This is same day season started in 2018!
Anyone experienced similar?
