# Description

Final density estimations per hexagon (approx. 14km2) in BC Albers.

Shape file name represents the bird species (e.g., ANMU = Ancient Murrelet) plus "w" (w = density estimates of birds on water only) or "sw" (sw = density estimates of combination of birds in flight and on water).

ANMU = Ancient Murrelet
BFAL = Black-footed Albatross
CAAU = Cassin's Auklet
COMU = Common Murre
CORM = Cormorants (Brandt's, Double-crested, Pelagic)
DARK = Dark shearwaters (Flesh-footed, Short-tailed, Sooty)
FTSP = Fork-tailed Storm-petrel
GREB = Grebes (Horned, Red-necked, Western)
LESP = Leach's Storm-petrel
lgGULL = large Larus spp. gulls (California, Glaucous-winged, American, Thayer's)
LOON = Loons (Yellow-billed, Common, Red-throated, Pacific)
MAMU = Marbled Murrelet
NOFU = Northern Fulmar
PFSH = Pink-footed Shearwater
PIGU = Pigeon Guillemot
RHAU = Rhinoceros Auklet
RNPH = Red=necked Phalarope
SCOT = Scoters (Black, White-winged, Surf)
smGULL = small gulls (Black-legged Kittiwake, Bonaparte's, Mew, Sabine's)
TUPU = Tufted Puffin


Field names represent, using ANMUw as the example: 
- first few ields represent summary fields (i.e., FID, Shape and Id)
- HexagonID = unique hexagon cell ID. Can use this field to join across species files.
- X_coord and Y_Coord = should be self explanatory. 
- spr_ANMUw = estimated Ancient Murrelet on water density estimates (birds/km2) in spring (April 2007, May 2007, June 2008)
- sum_ANMUw = same as above, except in summer (August 2005, 2006 and 2008)
- fal_ANMUw = same as above, except in fall (October and November 2007)
- ANMUw_AnAv = average across spring, summer, and fall density estimates
