The 8.8 mile trail that circles Barr Lake State Park near Brighton CO goes past several wildlife viewing stations. A boardwalk leading to a gazebo with a permanently mounted spotting scope for viewing the rookery area is located a little over a mile from the Nature Center parking area. Over 350 species have been observed in the park but birding has not been as good for the past several months because much of the water in the lake was drained to make repairs to the dam. Water levels are back to normal now and there were hundreds of American White Pelicans visible from the gazebo when I was there last month.
When I reached the gazebo, the pelicans were widely scattered throughout the trees along the distant shoreline. Later, activity in the water closer to the gazebo attracted several small groups of the pelicans. The activity of these groups attracted even more small groups until, eventually, every visible pelican was actively feeding relatively close to my location. With hundreds of active birds flying in different directions, it was difficult to select the subject of a photo. Ten of the more coherent images are presented here (1 above and 9 below). The sixth image below was taken with the Olympus OM-D E-M1 Mark II camera and 300mm f/4 lens, handheld. The 1.4x teleconverter was attached for the remaining shots.
