Bob Dunn finds some information on Sibley Guides website about the juvenile/immature Sandwich Tern bill coloration which might stir up more discussions about this interesting tern found in Hayward Marsh. Here is the link: https://www.sibleyguides.com/2007/08/sandwich-tern-bill-color-of-juveniles/?fbclid=IwAR0e1PS7dcTSMPX4WTDSbNvYtN_VO__MEKCUaltwbHjbG5qH4bjIAW7u3jI

And here is the link to images with different colors/shapes of presumed juvenile SATE or possible SATE x ELTE hybrid: http://www.martinreid.com/Main%20website/SATE.html

I have changed my eBird sighting from SATE to SATE x ELTE (with the comments that it could be as well a dark billed ELTE) and added 2 more photos. Here is the updated checklist: https://ebird.org/view/checklist/S57431258

Happy Birding,
