Habitats used during non-breeding months and . These factors may explain the lack of murrelet presence detections near cities where murrelet surveys have occurred. In the winter, the murrelets are grey, with white rings around their eyes. This map depicts the seasonally-averaged estimated relative abundance, defined as the expected count on an eBird Traveling Count starting at the optimal time of day with the optimal search duration and distance that maximizes detection of that species in a region.
