Yellow-rumped Warblers (Setophaga coronata) typically forage in the outer tree canopies at middle heights. They're active, and you'll often see them sally out to catch insects in midair, sometimes on long flights. Yellow-rumped Warblers spend the breeding season in mature coniferous and mixed coniferous-deciduous woodlands (such as in patches of aspen, birch, or willow). In the western U.S. and in the central Appalachian mountains, they are found mostly in mountainous areas. In the Pacific Northwest and the Northeast, they occur all the way down to sea level wherever conifers are present. Yellow-rumped Warblers put their nests on the horizontal branch of a conifer, anywhere from 4 to about 50 feet high. Tree species include hemlock, spruce, white cedar, pine, Douglas-fir, and larch or tamarack. They may build their nests far out on a main branch or tuck it close to the trunk in a secure fork of two or more branches. Occasionally nest are built in a deciduous tree such as a maple, oak, or birch.
I heard a Yellow-rumped Warbler singing nearby while looking for a spot to put the cache. The cache contains a log book and swag. You will have to bring your own autographing tool to sign the log. The cache is on a seasonal road not plowed during the winter. Don't forget to get the letter and number from the log and inside of the lid for the Bald Eagle puzzle cache.
