Holiday Beach Migration Observatory Essex Co., Ontario, Canada Fall 2003 Banding Summary
By Allen Chartier A total of 76 species was banded this year, the highest ever since we opened the station in 1997. The previous high was 73 species in 2001. A total of 1310 new birds, plus 89 recaptures was our second highest ever. The station was open a total of 44 days between 9 August and 23 November, which is significantly more than the high of 37 days in 1999. Two additional nets were added this season, which in addition to the increase in daily coverage gave us a significantly greater number of Net Hours (NH). This year's total of 4174 NH is significantly higher than last year's high of 3011 NH. The season total for birds banded per 100 NH was 33.5, which is the lowest ever in the past 7 years of our operation. The previous low was 2002 with 40.9/100 NH. Three species were banded for the first time at the station this year, Eastern Screech-Owl, White-eyed Vireo, and Eastern Towhee. Species missed this year included Black-capped Chickadee, Cedar Waxwing, and Blackburnian Warbler (3rd year in a row), Some numerical increases of many species were clearly due to increased coverage. Comparison of the number captured per 100 net hours this year to the previous 6-year average/100 NH is a better measurement. Using these figures, some numerical increases are actually decreases when the effort is taken into account. A good example is Golden-crowned Kinglet, with a season record of 162 (6-year average is 82.5) banded, while the capture rate was only 3.88/100 NH (6-year average is 5.41). Of the 73 species with previous banding data for comparison, 38 species showed no significant change, 30 species showed significant decreases and 5 species showed significant increases. Banders this fall included Allen Chartier, Bob Hall-Brooks, and Carl Pascoe. Steve Greidanus was a bander-in-training, and Rachel Powless was an able and tireless banding assistant. = no significant change < significant decrease > significant increase Data = 2003 total (6 yr avg), 2003 birds/100 NH (6 yr avg) Species Data = Sharp-shinned Hawk: 12 (4.8), 0.29 (0.32) - record = Cooper's Hawk: 1 (0.2), 0.02 (0.01) = American Woodcock 1 (1.0), 0.02 (0.07) = Mourning Dove 1 (1.0), 0.02 (0.07) Eastern Screech-Owl 1 (0.0), 0.02 (0.00) - new for station = Whip-poor-will 1 (0.3), 0.02 (0.02) > Ruby-throated Hummingbird 134 (37.3), 3.21 (2.45) - record = Red-bellied Woodpecker 1 (0.2), 0.02 (0.01) < Downy Woodpecker 5 (4.2), 0.12 (0.27) = Northern (Yellow-shafted) Flicker 3 (2.5), 0.07 (0.16) = Eastern Wood-Pewee 5 (2.5), 0.12 (0.16) < Yellow-bellied Flycatcher 8 (5.5), 0.19 (0.36) = Alder Flycatcher 1 (0.02), 0.8 (0.05) = Willow Flycatcher 2 (1.3), 0.05 (0.09) < "Traill's" Flycatcher 12 (11.0), 0.29 (0.72) < Least Flycatcher 1 (4.7), 0.02 (0.31) = Eastern Phoebe 4 (4.0), 0.10 (0.26) = Blue Jay 41 (22.8), 0.98 (1.50) = Tufted Titmouse 2 (1.0), 0.05 (0.07) < Brown Creeper 4 (6.0), 0.10 (0.39) = Carolina Wren 6 (4.2), 0.14 (0.27) = House Wren 4 (3.8), 0.10 (0.25) = Winter Wren 9 (5.3), 0.22 (0.35) < Golden-crowned Kinglet 162 (82.5), 3.88 (5.41) - record < Ruby-crowned Kinglet 137 (72.2), 3.28 (4.73) - record = Veery 9 (3.3), 0.22 (0.22) - record < Gray-cheeked Thrush 9 (16.0), 0.22 (1.05) < Swainson's Thrush 35 (29.0), 0.84 (1.90) = Hermit Thrush 46 (27.8), 1.10 (1.82) = Wood Thrush 1 (1.2), 0.02 (0.08) < American Robin 1 (3.5), 0.02, (0.23) < Gray Catbird 12 (8.7), 0.29 (0.57) = Brown Thrasher 1 (1.0), 0.02 (0.07) White-eyed Vireo 1 (0.0), 0.02 (0.00) - new for station = Blue-headed Vireo 4 (3.3), 0.10 (0.22) < Warbling Vireo 4 (11.3), 0.10 (0.74) = Philadelphia Vireo 4 (3.8), 0.10 (0.25) < Red-eyed Vireo 30 (22.0), 0.72 (1.44) > Blue-winged Warbler 2 (0.2), 0.05 (0.01) - record = Golden-winged Warbler 1 (0.2), 0.02 (0.01) < Tennessee Warbler 21 (21.2), 0.50 (1.39) > Orange-crowned Warbler 7 (1.3), 0.17 (0.09) - record = Nashville Warbler 64 (29.7), 1.53 (1.94) = Northern Parula 1 (0.5), 0.02 (0.03) < Yellow Warbler 2 (12.0), 0.05 (0.79) < Chestnut-sided Warbler 19 (21.8), 0.46 (1.43) < Magnolia Warbler 100 (75.0), 2.40 (4.91) < Cape May Warbler 2 (3.2), 0.05 (0.21) < Black-throated Blue Warbler 15 (28.3), 0.36 (1.86) < Yellow-rumped Warbler 25 (51.8), 0.60 (3.40) = Black-throated Green Warbler 6 (4.2), 0.14 (0.27) < Bay-breasted Warbler 2 (5.3), 0.05 (0.35) < Blackpoll Warbler 21 (25.0), 0.50 (1.64) < Black-and-white Warbler 13 (12.7), 0.31 (0.83) < American Redstart 26 (32.8), 0.62 (2.15) = Prothonotary Warbler 3 (1.3), 0.07 (0.09) = Ovenbird 17 (11.5), 0.41 (0.75) < Northern Waterthrush 7 (6.7), 0.17 (0.44) = Mourning Warbler 4 (1.7), 0.10 (0.11) = Common Yellowthroat 8 (2.8), 0.19 (0.19) - record < Wilson's Warbler 25 (19.2), 0.60 (1.26) < Canada Warbler 6 (7.0), 0.14 (0.46) > Scarlet Tanager 2 (0.2), 0.05 (0.01) = Northern Cardinal 19 (14.7), 0.46 (0.96) = Rose-breasted Grosbeak 4 (1.7), 0.10 (0.11) = Indigo Bunting 1 (1.0), 0.02 (0.07) Eastern Towhee 1 (0.0), 0.05 (0.00) - new for station < American Tree Sparrow 11 (9.7), 0.26 (0.63) = Field Sparrow 1 (0.3), 0.02 (0.02) = Fox Sparrow 6 (5.7), 0.14 (0.37) = Song Sparrow 10 (8.0), 0.24 (0.52) = Swamp Sparrow 7 (3.5), 0.17 (0.23) < White-throated Sparrow 50 (48.7), 1.20 (3.19) = White-crowned Sparrow 1 (0.3), 0.02 (0.02) > Dark-eyed (Slate-colored) Junco 29 (9.7), 0.69 (0.63) - record = Common Grackle 2 (0.7), 0.05 (0.04) < American Goldfinch 51 (33.0), 1.22 (2.16) Allen Chartier [EMAIL PROTECTED] 1442 West River Park Drive Inkster, MI 48141 Website: http://www.amazilia.net Michigan HummerNet: http://www.amazilia.net/MIHummerNet/index.htm "Allen Chartier" <[EMAIL PROTECTED]> Visit http://www.ofo.ca/ontbirdsguide.htm for information on leaving and joining the list.
