May 4, 2017 . . .
UPDATE . . . .
I remain an old guy without a PM colony, maybe worse, so far in 2017 --- only ONE fleeting (didn't even land) visit by an ASY-M about three weeks ago.
With three (more) days of cold (lows in hi 30s) and rain predicted here, maybe this is a good thing (for now).
Two nearby Subadult-Males have been reported by PMCA, one as close as 10 miles, so it's gotta be a matter of any day now that subbies show up at my site . . . or there really is something seriously wrong this year.
BTW - I have instituted - VERY CAREFULLY AND PRECISELY - the PMCA-endorsed Emergency Tree Swallow procedures, by moving the shepherd's hook Tree Swallow (occupied) gourd to EXACTLY 35' of my gourd rack pole. The TS pair (well, the female) has built their usual comfy looking - and back-placed, safe and feather adorned nest (no eggs as of yesterday) . . . wish Martins built a better nest . . . they could take a lesson from their Tree Swallow cousins . . . fearless little rascals with humans, e.g., my granddaughter and I can nearly touch them . . . but I digress.
The TSs are doing EXACTLY (for now) what the Emergency Procedures say they will do, i.e., run off ANY and EVERY TS that dares approach their gourd OR THE PM GOURD RACK. For example, if THREE TSs are observed in my area, the other two are ACTIVELY running off #3.

But . . . but . . . I still fret over what will happen when (if?) "my" subbies arrive, i.e., will the TSs chase off the PMs? They sure as heck perch on the PM gourd rack . . . although . . . I've never seen them run off any bird species but their own, i.e., TSs.
So . . . we (my granddaughter and I) wait . . . and watch . . . a lot.
Best of luck to the other PM landlords, both real and wannabe.
