Migrants at Fort Mason this morning

David Assmann

A nice little pulse of migrants moved through Fort Mason this morning, including a WESTERN KINGBIRD, a PACIFIC-SLOPE FLYCATCHER and a RUFOUS HUMMINGBIRD (normally indistinguishable from Allen's but I managed to get a picture of the notch in the R2 tail feather). A SPOTTED TOWHEE and a WILSON'S WARBLER were also either migrants or locally dispersing birds.
