Water Crib Action

Wilson Avenue Crib

If you’ve been to Montrose you’ve probably noticed the structure due east on the horizon that looks like it’s floating on Lake Michigan. This is the Wilson Avenue Crib and it was part of the water distribution system for Chicago. The cribs pump water to the filtration plants, also along the lakefront. The filtration plants purify the water and distribute it to the city and nearby suburbs for consumption. The Wilson Avenue Crib is no longer operational but several species of birds are making good use of it. The dark shapes in the photos are Double-crested Cormorants and they nest on the crib. State endangered Peregrine Falcons have also nested there.

I took this photo with my digital camera and Questar telescope in June 2019, a technique known as digiscoping. To read more about how I digiscope, see the Digiscoping with a Questar page on my main birding website, The Orniphile. The Wilson Avenue Crib is about 2 miles offshore.

Ice Formations

Birding has been slow this winter at Montrose. My best days have maxed out at between 20 and 24 species. This is typical but in some years we at least have Snowy Owls to keep us entertained and to pass the time until spring and migration arrive. Not this year. Not one Snowy Owl has been reported at Montrose this winter.

Today, February 22, was no different; I tallied 24 species in 90 minutes of birding, but the ice formations on Lake Michigan made the long walk out onto the fishing pier worthwhile. I’m always impressed by the geometry of these formations. In this picture, one of the pieces in the foreground looks perfectly square, the piece above it looks perfectly rectangular, and the large piece to the left looks trapezoidal. Nature’s artwork.

Burbot, November 16, 2015

This morning I saw a strange fish at Montrose, a fish I’ve never seen before. I’m familiar with most of the local fish and I can at least place them into larger categories, e.g., salmon, bass, pike, gar, but this one looked nothing like any fish I’ve ever seen in the wild. It reminded me of a cod and I vaguely recalled that there is a freshwater cod-like fish found in the Great Lakes called a Burbot. When I got home I did some research and my mystery fish matches up very well with a Burbot (Lota lota). According to Wikipedia, Burbot are benthic in nature, which means they inhabit the lowest levels of a body of water, which might explain why I don’t see them.

Beaver, October 11, 2015

The best bird this morning wasn’t even a bird but a Beaver. I saw this one swimming south in Lake Michigan, hugging the fishing pier. I’m always surprised how big Beavers are when I see them in the wild; I’d say this one was 2.5 feet long and maybe 40 pounds. There really isn’t any suitable Beaver habitat at Montrose so I think most pass through and don’t stay long, though there is evidence in the form of chewed branches that they use the Dunes.

October 31, 2014 Storm

I went over to Montrose this afternoon to see the wave action on Lake Michigan from the storm that went through. I’ve lived in Chicago all my life and I’ve seen some impressive weather but this storm has to rank near the top in terms of violence and intensity. A large part of the dunes at Montrose Beach was flooded. At times part of the fishing pier was under water. Waves were crashing 20-30 feet high against the fishing pier. Lake Michigan was roiling. I even saw a few birds, including a Northern Harrier flying south over the lake.
