Fig 3. Temporal trends in the number of Marbled Murrelets counted at radar stations distributed through six Conservation Regions in British Columbia, 1996–2013.

Thick lines indicate predicted means from trend model, with 95% credibility intervals that depict the within-Region yearly-variation. Colour and shape of symbol indicate radar tilt: 0 (which include 0 and 5.2 degree tilts, open squares), 10 (which include 10, 11.3 and 12.8 degrees, red circles) and 25 degrees (blue triangles).
