  1. The adult Black-legged Kittiwake in Calgary is noteworthy for several reasons: 1) There are less than 20 accepted records for the province, 2) It is the longest staying kittiwake for Alberta (with most birds gone within a couple of hours, 3) It has been lingering at a pond at a landfill and has been seen picking through and eating waste (James Fox pers comm.). I don't know of any previous reports of kittiwakes feeding, or attempting to feed, at landfills. 
  2. Nick Ramsey reported a putative Kelp x Herring hybrid from the Chandeleur Islands in St. Bernard Perish, Louisiana on 20 April 2021. Adult type. Upperparts intermediate, with a prominent bulbous-tipped bill, square p10 mirror and slight dusky wash on the primary coverts. In addition to this individual, another 3 suspected 1st/2nd cycle type hybrids may have been present, tending toward Herring.
