This rare flotilla of nine loons enjoying Deer Lake's pristine waters was captured by Dave Chatterton.
Deer Lake Loon Count 2011
Deer Lake 2010 Loon Survey
The survey was taken on July 12 2010 by Joan and Gerry Ratzlaff- Trish and Jim Bogenreif and Rob and Barb Baker
The count was 38 adults 6 chicks (9 chicks hatched)
By observing during the nesting season we counted 9 chicks but three were lost before the survey of the 9 successful hatches were from nesting platforms.
Previous counts '05 32 adults-4 chicks '06 45 & 4- '07 43 & 4 '08 43 &2- '09 31 & 5 (7 hatched)
Necropsy Results from 2009
We sent one dead adult loon and 1 chick to the DNR to determine cause of death.
Results--the adult cause of death was determined to be an infection. Symptoms of infection severer enough to cause death were present, however the type of infection was undetermined. There was no evidence of lead toxicity. The chick cause was determined to be from trauma. The chick had hemorrhaged throughout the body cavity, injuries consistent with an attack from a predator.
2009 LOON COUNT
The Loons are Nesting! Do Your Part to Protect Loons!
Watch loons from at least 500 feet away. Use binoculars from a safe distance.
Use non-lead fishing sinkers and jigs. Ingesting one sinker or jig will kill a loon.
Avoid islands before July 15th of each year. Human activity near a nest can cause the parents to leave it allowing the eggs to cool and die in as little as 15 to 45 minutes.
Keep dogs and cats away from loons and nests. Pets disturb nesting loons and destroy loon eggs.
Do not use fertilizer on shorelands. Fertilizer that finds it’s way into the lake through runoff or leaching increases aquatic plant growth, making it difficult for loons to swim and find food.
Be a responsible boater. Never chase loons or run motorboats over areas where loons have been seen. Loons and loon chicks have died from being hit by boats and propellers.
Don’t forget to look for the loon! If you know of a nesting pair on Deer Lake please notify Joan and Gerry Ratzlaff,
(218) 246-9652, or e-mail: JoanAndGer (at) aol.com
The DNR is planning to collect dead loons again this year and determine the cause of mortality when possible. If you find a dead loon, put it in a plastic bag and chill as soon as possible (freezer is fine) to stop decomposition. Contact Pam Perry- (218) 833-8728 or pam.perry (at) dnr.state.mn.us she will arrange transport to a DNR office.
