Glaucous-winged Gull, Pueblo Reservoir

[David Tønnessen]

Hi all,

Edward Landi and I have been looking at a 2nd cycle Glaucous-winged Gull here at Pueblo Reservoir's South Shore Marina. It's been flying around aggressively chasing other gulls and occasionally landing briefly. Look for a massive gull with pale uncontrasting wingtips and a smudgy black bill. Pale and off-white overall. 

Other cool birds here include a first cycle Nelson's Gull (Glaucous x Herring Gull hybrid), the resident Great Black-backed Gull, and more common gulls of other flavors. Also Pacific and Common Loons, and resumably a Red-throated Loon still around somewhere.

Good birding,

David Tonnessen
