Lake Superior Tidal Lagoon Birding

Well … not exactly. Instead on this day with a temperature of 37F yet rain, sleet, thunder and lighting as air masses reach Lake Superior, it is time to finish up my Costa Rican posts, and wish I was in that sunny, warm location. A great place for birding are any Tidal Lagoons you find. These small ponds get recharged almost daily with water when high tides breach their “sand barriers”. The incoming tides bring food into the lagoons … fish and other yummies for birds. When the tide recedes the small fish and other delicacies are trapped which makes for each fishing / hunting / etc. on the part of birds. Should the lagoon have a small fresh water source during Guancaste’s “rainy season”, so much the better! While in Costa Rica I went birding at tidal lagoons at Zapotal, Las Catalinas, and Playa Potrero (featured in this post)

I will add that while the North Shore of Lake Superior’s rocky coast does not have any lagoons, the south shore with its much milder landscape has some really nice wetlands where rivers empty into the big lake, and those are also great spots to go birding … just no tides!

A Foggy Day in London Town … Birding

Yesterday I went out birding after church … ignoring the heavy fog warnings. I wanted to pull three birdsong listening stations off the trails before the rains started once more. As with the day before, find a bit of open water and one fill find some waterfowl.

Soon the trails in the Duluth area will be snow and ice free, but such was not the case yesterday as I dealt with 1/2 foot of sloppy snow / slush.

Yesterday morning the sun actually shone bright, in short it was not “dreich” (read definition from the BBC)! I left the house at 7:00 am on an “open water quest”. I reasoned if I found open water, I might find birds migrating back to the Northland. Just when it appeared my quest would be a failure … all the lakes and ponds were still iced shut with zero “black ice” … I checked the Rice Lake outlet. Current at the lake’s outlet created a small area of open water, and waterfowl were there aplenty!

One of the species in greatest abundance were Trumpeter Swans, and love was in the air (or at least on the water)!

Although Rice Lake is not a suitable breeding pond, A Trumpeter Swan asks the Canada Swan to move along! Swans and Geese don’t get along.


Apparently this duo is a couple!

Was it as good for you as it was for me?!
