Photos May-July

by Carl Strang

It’s been a busy field season, and I have fallen way behind in blog posts. I’ll catch up eventually, but today will share a smorgasbord of photos from May through July.

This barred owl appeared during a walk through St. James Farm Forest Preserve. I believe I had come close to its nest tree.

This dragonfly I encountered at Houghton Lake in Marshall County, Indiana, was a bit of a puzzler. I eventually concluded it was a somewhat odd widow skimmer.

SJF March Summary

by Carl Strang

Weather in March at St. James Farm Forest Preserve was variable, but on the whole was relatively warm with frequent rainy periods. At the beginning of the month there was a little lingering snow on the ground, and ponds were frozen, but all of this quickly was gone.

I used my old GPS unit to map my survey routes and to locate positions of previously discovered cavity trees that might harbor a great horned owl nest. One of these indeed proved to hold the nest, and the female still was present on March 25, late enough to indicate that hatched young were being brooded. Two attempts to find displaying woodcocks were unsuccessful, but during the first evening visit on March 17 I heard what I thought was a short call by a barred owl in the eastern portion of the preserve. Scott Meister reported hearing the species in the forest one evening the following week. No pileated woodpecker observations in March, but recent observations in preserves to the north along the West Branch suggest that the bird or birds seen here earlier may be wandering widely. Canada geese were down to small groups and pairs early in the month. By March 31 a nest was under incubation on the small island in the pond below the former house site.

Many killdeers were displaying in the restoration project area around the stream early in the month, but these were down to just a few individuals by month’s end. Bird activity generally increased as the season progressed, with the first cowbirds arriving March 8, a pair of hooded mergansers and 2 pairs of wood ducks present in the pond in the NW corner of the preserve for much of the month, sandhill crane flocks frequently passing overhead, a northern flicker and the first golden-crowned kinglets appearing on March 14, tree swallows on March 25, and two pairs of green-winged teals in the restored stream on March 26.

A shed antler found on March 17 in the forest near Winfield Road matched the buck photographed in the same area on November 1.

The first snake observed on the preserve was a midland brown snake on March 29. That same day several painted turtles were sunning in the eastern pond.

Western chorus frogs began singing on March 11, and ultimately displayed in three locations. The largest number were in the fringes of the eastern pond, and many also were in two temporary ponds in the meadow north of the entrance drive. Numbers of bullfrogs, large and small, had emerged by March 21.

The first butterfly of the year was a mourning cloak observed on March 21. A cabbage white appeared on March 29. The former overwinters in the adult form, the latter as a pupa. Several small brown moths were active on the forest floor on March 31. One was photographed and appears to be a tortricid, close to several similar species of Pelochrista or perhaps Eucosma.

Silver maples were blooming by March 11, and spring beauties by March 31.

Spring beauties were the first native herbaceous wildflowers to bloom at St. James Farm in 2016.

Restoration clearing of the forest was completed by mid-March, and a new set of stakes presumably marking the new trail route was placed in the final week.

Some Bird Notes

by Carl Strang

There had been no sightings of Mayslake Forest Preserve’s great horned owl fledgling since the day after it left the nest tree.

One of my last views of it, on May 3.

On Saturday evening I was at Mayslake to see First Folio Theater’s production of Shakespeare’s Merchant of Venice on the outdoor stage. During the intermission I took a quick walk to the east end of the preserve, and was rewarded by the peculiar screeching whining contact calls of a juvenile great horned owl. Still flapping!

Another owl update was this newly molted feather I found during last week’s creek walk.

Proof that the barred owls are in their usual territory at Waterfall Glen Forest Preserve.

Earlier in the season one of Mayslake’s willow flycatchers gave me a photo op.

This is a bird of open fields with scattered shrubs. Usually one pair nests at Mayslake.

Birds are much quieter now that the breeding season is nearly done.
