Birders,
About 8:40 this morning, a juvenile Olive-sided Flycatcher was seen flycatching from a large dead cottonwood tree in Callahan Open Space adjacent to North Open Space in Louisville.
It was located NE of a dirt path that follows an irrigation ditch north from K.Helart Park and was ~ 0.3 miles from the park.
Photos to follow with eBird checklist.
