Jan 17, 2013: Wolf's 2012 Annual Species Summary

Wolf Oesterreich tirelessly patrols the park, documenting the wildlife and weather daily - a true Friend of Ada Hayden Heritage Park! 12/19/12 (Kevin Kane)

I recorded a total of 189 species (plus 8 sp.) at Ada Hayden Heritage Park in 2012, ranking this year as the 8th highest among 16 years of records.  The mean of all the years is 167.1 species, with a range of 51 (1997) to 206 (2011).  Of course, if one were to remove the 1st year which only represents one month, the 15-year mean is 174.8 species, with a range of 128 (1998) to 206 (2011).  Three species (Wild Turkey, Least Tern, & Tufted Titmouse) were added to the List, which now totals 260 species.  Fall migration was pitiful, with no Greater White-fronted Geese, scoters, and loons.  Even waterfowl numbers were down.  Drought and heat conditions were probably a factor in fewer shorebirds, warblers, and blackbirds.  Notably absent from the List this year include the following: Surf Scoter, White-winged Scoter, Black Scoter, Long-tailed Duck, Eared Grebe, American Bittern, Cattle Egret, Rough-legged Hawk, Hudsonian Godwit, Marble Godwit, Stilt Sandpiper, Short-billed Dowitcher, Long-billed Dowitcher, Black Tern, Red-headed Woodpecker, Bell’s Vireo, Blackburnian Warbler, Western Meadowlark, Yellow-headed Blackbird, Great-tailed Grackle, and Purple Finch.
