Carpentersville Dam – 12/14/2016

NOT A WBC TRIP

Target species : Barrow’s Goldeneye, Iceland Gull, Lesser Black-Backed Gull, and Thayer’s Gull

Unexpected sepcies : Redhead and possible California Gull

Along the way to the dam, we stopped at the Otto parking lot to find eight Bald Eagles flying around. After a short stop there, we drove up to the Dam to try to find some rare Gulls. We got to the overlook and we found the 1st year ICELAND GULL and three more Eagles. At the dam, we saw that up the river at Fox River Shores FP, there were lots more gulls. So, we decided to check  it out. The hike to the point was terrible with the very cold wind blowing straight in to our faces. When we got to the point, we found about 75 to 100 Gulls sitting on the ice. One Gull was a possible California because of the bicolored bill (red gonydeal spot before black ring) and in between the size of a Herring and a Ring-billed. Those were the only field marks I could make out. Also, I could have possibly mistaken the size and it could have been a very late transitional plumage third year Herring Gull. So on ebird I will only put Larus spuh. But still a very intriguing bird that I think others should check out. After a slightly more pleasant walk back, we headed over to the Fox River in West Dundee to see if the Barrow’s Goldeneye was there. Once we got there, we saw hundreds of Canada Geese, wild and domestic Mallards, seven Common Goldeneye (with no Barrow’s), and some of the gulls from the dam (including the 1st year ICELAND).
