Hi all,

Nova Scotia Migration Count May 12, 2007

 

The Annual Nova Scotia Migration Count was held this year on May 12, as always on the second Saturday of May. The weather was mixed with early morning cloud and showers in many areas followed by gradual clearing, bright sun, and higher winds later in the day.  631 Nova Scotia birders walked the trails, watched feeders, cruised our waters, listened in the early hours and rode bikes, motorcycles and ATVs. One adventurous birder rode a horse.  All this effort tallied 208 species and over 93,000 individual birds.

 

The species count was average but the overall count of individual birds was 18% below the previous eight year average, although up 15% from last year.   Continental weather patterns weeks and even months ahead of our count day play a significant role in determining the overall numbers and mix of species we observe.  Great Cormorant was up 73%, Black Scoter up 140%, and Ruby-throated Hummingbird up 82%.  Pine Siskin is down 93% and Red-breasted Nuthatch down 52%. Both species have likely relocated due to a change in local food supply. The winter finch numbers are down as well with White-winged Crossbills reduced to six birds in the whole province.  The good news is that the slide in the Evening Grosbeak population is abating and may even be recovering somewhat. Sadly the House Sparrow continues to decline.

 

Highlights of this year's count were 65 Northern Fulmar, Brier Island; two Snowy Egrets, Queens and Shel; five Little Blue Heron, Col, Inv(2), Rich and Shel; Green Heron, Lun; two Barrows Goldeneye, CBRM; 13 Snow Geese, CBRM;  one Red-shouldered Hawk, Inv; four American Oystercatcher, Shel; two Laughing Gull, CBRM; nine Roseate Tern, Shel; Little Gull, Pictou; two Common Nighthawk, Guys;  two Red-bellied Woodpecker, HRM, two Northern Rough-winged Swallows , CBRM, Eastern Bluebird, Cum; eight Wood Thrush, six in CBRM and two in Inv; Warbling Vireo, Kings; Scarlet Tanager, Kings; Summer Tanager, Lun; two Orchard Oriole, Cum and Digby.



This the annual year over year summary: http://hanstoom.com/NSMC2007Annual.htm



This the county summary: http://hanstoom.com/NSMC2007County.htm



I've looked at all our birds for the last nine years and although some populations are down this year, they have also been down in previous years and bounced back. Not much can be said other then there is no pattern for most species  I've plotted 5 graphs which are now available for viewing on the website, including four species that are currently of concern or are undergoing a major populations shift.

1) Migration Intensity on Count Day-shows a slight decrease in numbers but probably no cause for alarm, especially since this year shows a recovery.

2) Red-breasted Nuthatch-shows the lowest population in the last nine years confirming the field observations of most of us.

3) Evening Grosbeak-the precipitous decline in population seems to have reversed itself this year so next year will tell the story.

4) House Sparrow-this is all bad news since the population continues to fall as it has been all over the continent.

5) Pine Siskin-our population peaked in 2005, remember all our busy feeders and niger bills. Well this year the lowest population of the last nine years exists.

The graphs are here: http://www.hanstoom.com/NAMC/Analysis.html
 

I congratulate and thank all of this year's participants. Keep up the good work and we'll do this all again on May 10, 2008.
