The 119th CBC in Arkansas

Weather is always a factor for the Christmas Bird Count, but this year was the second record mildest year in a row within the last 12 years.  Only 10% of the counts were moderately impacted by wind or rain and 10% were severely impacted by rain or flooding.  A new 13% impact to the counts was the partial government shutdown, which cost counts their observers, transportation and especially access.  Overall 33% of the counts were impacted in some form, which was 8% below the 12-year average. 

In Arkansas 30 counts were submitted with 13 counts having more than 90 species.  Long expected, Lake Dardanelle had the high species count of 118.  Other counts over 90 species were:  Pine Bluff (115), Arkadelphia (109), Holla Bend N.W.R. (107), Hot Springs N.P. (103), Lonoke (102), Conway (99), Little Rock (97), Big Lake N.W.R. (95), White River N.W.R. (94), Fayetteville (92), Wappanocca N.W.R. (91), and Fort Smith/Moffett (90).  The high species count of 118 was average.  Sylamore Ranger District had the most new or unusual species (7) and Mississippi River S.P. had the most species high counts (20).  An amazing five counts set new species highs; Big Lake N.W.R. (95), Crooked Creek Valley (83), Lake Ouachita (54), Mississippi River S.P. (88), and Sylamore Ranger District (65).  Fayetteville had the most hours (78.5) and the most observers (47).  The total of 153 species statewide was 13 species below average and the worst in 15 years. 

Welcome to two new counts, Bella Vista/Bentonville/Centerton and Pond Creek N.W.R.!

The numbers for the following bird highlights are normalized by dividing with the party hours.  The best number of species occurred 12/25-12/30.  The best number of individuals occurred 12/31-1/5.  Statewide-total number of individuals (1,490,219) was 50 percent above the ten-year average.  The best number of species occurred in the Magazine Mountain area, followed by the Grand Prairie and the South Central/West Gulf Coastal Plain eco-regions.  The best number of individuals occurred in the Grand Prairie eco-region, followed by the Mississippi River Alluvial Plain and the Arkansas River Valley eco-regions.  Lake Dardanelle had the most individuals (540,257). 

In the broad groups, geese were 396% above average (12th year in-a-row above 200% and a 66-year high); and semi-hardy waterbirds were 137% (5th year in-a-row above 125%); shorebirds were 39% below average and the worst in 17 years; grassland species were -60% (a 66-year low, largely because of low Eastern Meadowlark numbers); blackbirds were -93% (for the 7th year in-a-row below -70%); western species were -62% and the worst in 11 years; frugivores -97% (for the 5th year in-a-row below -90%); and upland game-birds -70% (a general decline since the 1980’s with cyclic highs and lows within the decline).
