Cobirders,
Back on 12/14, Steve Barlow found a Black and White Warbler 400 meters west of I-70 along Clear Creek. Then, as I was scouting for the North Jeffco CBC, I found a Black and White Warbler at the west parking lot just east of I-70. A friend of mine was looking along with several other birders west of I-70 when I told him I had a Black and White east of I-70 and they were able to see it as well.
On 12/19, I was on my CBC and found the Black and White Warbler about 300-400 yards west of I-70. I spoke with a couple of fellow birders who stated they just had it east of 1-70 lot again. What????? This didn't make sense!! This warbler I found had a much more striking appearance than the one I had days earlier. I ran into another birder who just had it to the east of I-70 and I mentioned I had it a great distance from where everyone else was reporting it that morning. I stated if it was possible there were two. The first three photos are of the bird east of i-70 on the 14th and the second four are the bird well west of I-70 on the 19th. What do you think???? I know what I think :)
