Hi all,
There have been two swans seen at Stearns Lake (Boulder Co.) and the "Brainard Drive Pond" (Broomfield Co.) for the past two days. There is a significant size difference between the two, with the juvenile being much smaller and having a thicker, straighter neck. I'm quite sure the young bird is a Tundra. The adult is definitely a Trumpeter. Chipper has some nice photos: https://ebird.org/checklist/S126234533
