For the last three years, and along with 4-5 volunteers, I have been doing a 
study on the roosting habits of Double-crested Cormorants at Tommy Thompson 
Park (TTP, aka The Spit) before they start egg laying and before they are 
24-hour residents at Tommy Thompson Park. The work is not hard but it comes at 
an hour when we have found it difficult to be in the field, i.e., dinner time 
and early evening family responsibilities…. So, we need more help! I am looking 
for bird-watcher volunteers who can scour the trees, rock jetties/breakwalls 
and shoreline of Lake Ontario, on the Toronto Islands and the shoreline areas 
to the west of them, looking for roosting cormorants. For the next 2-3 weeks, 
cormorants arrive at their TTP breeding areas, before sunrise, from the 
west/southwest---but I have no idea from exactly where. I am quite sure they do 
not roost on the water (but I am willing to be proven wrong) ---as they never 
do in the late summer/autumn. They may be roosting in trees on the south or 
west shore of the Toronto Islands, or on the extensive breakwalls of Sunnyside 
or in shoreline trees up the Humber River or along the shoreline out to Mimico 
or Long Branch. Right now, cormorants have just arrived back at their TTP 
breeding area this past week-end but in the next 2-3 weeks, thousands more will 
return and by mid-April they will be roosting overnight at their colony site. I 
would like to know where they roost between now and then.

Many thanks for your help,
