Sierra Club - COS
Montrose Beach Cleanup

with Nature Walks at
Montrose Point Bird Sanctuary,
Lincoln Park, Chicago
Cook County, IL
17 September 2011

Christine Williamson organized a series of nature walks at Montrose Point Bird & Butterfly Sanctuary in conjunction with the 17 Sep 2011 Sierra Club Montrose Beach Sweep. Four different walks took adults and school kids through the natural areas at Montrose Point. Seen on these walks were 48+ species of birds, 3 species of mammals (excluding Homo sapiens and Canus domesticus), 7 species of butterflies, and one species of dragonfly. Lists of what we saw appear at the bottom of this page, along with a number showing how many of each species were found.

Here is a group from the Goudy School on one of the nature walks.


On the beach were Sanderlings feeding on invertebrates in the algal mat.


Also in the algae next to the water's edge at the beach were four Semipalmated Plovers. Here are three of them.


One more shorebird that was present there was this Semipalmated Sandpiper. It is a juvenile bird, one born earlier this summer. You can tell this by the crisp, clean feather edges that make a nice pattern on the bird's upperparts.


At the waterfall in the middle of the big meadow at Montrose Point, we saw this Magnolia Warbler bathing.


Walking through the meadow one was sure to see Monarch butterflies. Here is one getting nectar from a fall-blooming aster.


Tougher to find is the butterfly's larval form, better known as the caterpillar. However, Christine Williamson spotted one on the leaf of a milkweed plant. Milkweed is the food plant for the Monarch caterpillars. Also on the leaf was a grasshopper.


Here is a closer look.


Another type of butterfly that was seen was the Orange Sulphur. Here is one, also enjoying the asters.


Finally, here is a Fiery Skipper, a small and fast-flying butterfly.
