[cobirds] Parula and Prothontary on CU Boulder campus

Hello all,

This morning, Matt Hofeditz found a Northern Parula on the CU campus, and later today Thomas Heinrich found a Prothonotary Warbler in the same tree with it. The two birds were seen together until dark.

Their favorite tree seems to be an oak with yellow leaves at the NE corner of parking lot 310, which is on the NE corner of Regent and Broadway in Boulder. Paid public parking is available at the Center for Community (C4C), which is just two buildings farther to the east on the north side of Regent.

As Dave Leatherman always reminds us, November warblers that hang out in the same area are always exploiting some kind of food source. This particular oak tree, like many oaks at this time of year, seems to have a sticky substance on its leaves that attracts hornets (and also rare warblers). I'll let Dave say what he thinks might be going on. But if the tree is feeding them well, these two warblers might hang around for a little while. Both birds venture to the surrounding trees as well.

For those who might come to Boulder County from elsewhere: the juvenile Yellow-crowned Night-Heron also continues at Pella Crossing park near Longmont. It hangs out around the NW corner of the easternmost pond, where it usually either hunkers down in the woody vegetation along the waterline, or else prowls the grass right next to the walking trail in plain sight.
