Hi Elizabeth and others,
 
The 'estimated' population for whatever region is being asked about is
based on the results of Breeding Bird Surveys (BBS). There are about 30
in Nova Scotia I believe. 16,000 (individuals not pairs) is not all that
large an estimate for Belted Kingfishers really, when you consider a
species such as American Robin will get you an estimated population of
3,000,000 for Nova Scotia. Also, it looks to me as though the estimated
number is +/-  %20.
 
As far as the long term trend goes, you can go directly to the BBS trend
analysis page and have a look at the data. It is found at:
http://www.mbr-pwrc.usgs.gov/bbs/trend/tf06.html
 
Since we're talking about Belted Kingfishers, the trend in Nova Scotia
over the last 40 years is -4.67% (p=0.01) 
 
All the best,
 
Lance

	Hi all,
	 
	I was checking / deleting / sorting my old emails and came
across Peter  deWitt's enquiry, which went unanswered.  He was wondering
about 16,000 kingfishers in Nova Scotia. My opinion is that the number
is pretty too high.  If so, we'd see them everywhere just like
starlings!  Here is Peter's email dated on December 6th below: 
	...............
	 
	December 6, 2007
	 
	I recently entered a discussion on Kingfisher population in Nova
Scotia.
	
	Using the website here:
	
	http://www.rmbo.org/pif_db/laped/PED3.aspx
	
	There is a estimated 16,000 Belted Kingfishers in NS.
	
	Would anyone happen to know if there is more reliable estimates?
Is
	there comparisons of Belted Kingfisher populations in NS over
the
	years?  Is the population thought to be declining or expanding
now?
	
	Also, on the HRM website for the coat of arms, it says that the
	Kingfisher is there as a "symbol of industry", but I could not
find
	out how or where it became a symbol of industry, or if other
locations
	use it for the same symbolic purpose.   Any ideas?
	
	
	Cheers,
	Peter
