We walked half of Lost Valley Trail at Weldon Spring Conservation area yesterday (5/10) to do our annual bird count of the area. We went straight at the "Y" and then turned right to follow the trail over the little creek. We followed the trail until we reached the Center Road. We went down the Center Road to the "Y" and back to the Parking Lot. Monday, weather permitting, we will do the other half of the Trail.
Little Femme Osage Creek and the other creeks had ample water but were not in flood. The tree foliage was lush and dense and there is a lot of undergrowth this year. The trail has much more shade than even last year.

The temperature at the start was 15 degrees below last year's and the ending temperature was 17 degrees below last year's. Many of the warblers and vireos were found by sight not by song. It seemed that there was less birdsong but more birds than last year. Perhaps the colder temperatures tend to suppress the song.
