Arm chair subtraction, or even better swap possibly?

Nothing of note as I've not birded beyond the confines of the yard the past 2 weeks.  Weather has been less than spring-like.  The only thing of note is I received an e-mail that the Buff-breasted Sandpiper from 4/16/2017 was flagged as potential Ruff.  A huge bird for this area.  First in the 8 counties around here, according to eBird.  I don't have high hopes that it gets approved by the MBRC.  I posted to Whatbird.com and to Birdforum.net and got a couple positives, as well as an e-mail, one saying looked okay for BBSA and another saying maybe Ruff but they wouldn't vote positive on it.  Bird would be in the upper left.  Definitely isn't a Pectoral Sandpiper as the shape in flight is way off.  

April 7th the 4 American Robin hatchlings were present in the morning, but gone later in the afternoon.  Didn't see any sign of an attack, and have only seen a couple of juvenile Robins since then.  Plenty of hiding places in the woods, so they may have just skipped town.  April 15th a Red-tailed Hawk successfully caught something at the woodpile.  I couldn't tell what it was though.  Looked small and black, so it could have been a bird.  Not sure why it would have been near the woodpile though as no place for it to hide there.  

Only other "exciting" things of note were a Scarlet Tanager and Yellow-billed Cuckoo added to the year list for the yard.  With some Chaos continuing going to be rough to find a Dickcissel or Alder Flycatcher to add to the list this month.
