Grant Woods

Leave a comment

Grant Woods is an extensive forested area with some shrubland in western lake county. In winter it is a good place to check for winter finches in the extensive pine stands of the North Unit. There is also a nesting Cooper’s Hawk in this area most summers. Northern Shrikes also like the tall shrubs bordering the grassy areas. I have had Purple Finches and Brewer’s Blackbirds here during fall migration and the South Unit is one of the better places for Fox Sparrows during the winter. The North Unit is especially good for warblers in the spring as the blossoming crabapples attract a multitude of insects for them to feast on. I had 20 warbler species here in May in 2011 on a nice sunny morning following the passage of a warm front. These included Black-throated Blue (2), Golden-winged, and Connecticut. It can be an electric place during spring migration. In the summer I have had breeding Blue-winged Warbler, Pine Warbler, Ovenbird, Wood Thrush, and Broad-winged Hawk. It is also my favorite spot for migrating Common Nighthawk. The open area south of the small lake has had summering Clay-colored Sparrow.

Siloam Springs State Park

2 Comments

Siloam Springs State Park is home to three highly sought-after species in Illinois: Worm-eating Warbler, Bewick’s Wren, and Chuck-will’s-widow, though Bewick’s Wren has not been present since 2014. Worm-eating Warbler can be found in almost any of the ravines found throughout the park, but can be very easily found at the parking lot indicated (Red Oak Trail) on the map. Also note that the county line goes north-south right through that parking lot, and walking east on the trail takes you immediately into Brown County.

Bewick’s Wrens once nested for several years in the vicinity of the Headquarters building, specifically around the equipment storage area, as indicated on the map. Being familiar with it’s song will greatly help locating it.

Other species found in the park include Barred Owl, Eastern Whip-poor-will, Hooded Warbler, Kentucky Warbler, Cerulean Warbler, Yellow-throated Warbler, Ovenbird, Northern Parula, Summer Tanager, Wood Thrush, Pileated Woodpecker, Red-shouldered Hawk.

Bewick’s Wren has also been found at the Benville Cemetery about 3 miles east of the park boundary, at the intersection of Co. Rd. 255E and Co. Rd. 175N. (also marked on the map).

Chuck-will’s-widow can be found near the Buckhorn Unit parking lot, off County Rd 400 North.

Cap Sauers Holding Forest Preserve

1 Comment

Cap Sauers Holding is one of the larger wooded areas in the Palos Hills forest preserves of southwest Cook County.  It is bordered by State Route 83 to the north, 104th Ave. in the east, McCarthy and Ford Roads to the south and private land to the west.  It is primarily a hardwood forest, sometimes savannah forest in character (open) and has areas of more open scrub.  It is crossed by several trails including the Green Trail that runs more or less east-west along its south border along Ford Road, where it is easily accessed.

The Green Trail gives access to two other trails: the Blue Trail that runs almost directly north from Ford Rd. to Route 83, and the Yellow Trail that makes a loop on the east side of the preserve and connects with Swallow Cliff FP on the south and Teasons Woods on the north (across 104th Ave.).  I usually park along Ford Road to access the trails but you can also park at Teasons Woods or Horsetail Lake FP near where the Yellow Trail crosses to Swallow Cliff.  Right along Ford Road listen for Summer Tanagers that have been found here the last few years.  Near where Ford Road makes a curve to the southeast (west of the caretaker’s house and Bergman Slough) the Green Trail is close to the road.  Go right on the trail.  You will first come to the Blue Trail.  Along this trail you can get Blue-winged Warbler, Ovenbird, Yellow Throated Vireo and Scarlet Tanager.  If you continue on the Green Trail the trail curves south bringing you close to the road across from Bergman Slough.  Red-headed Woodpeckers and a Yellow-throated Vireo have nested in this area for many years.

The Green Trail then heads northeast towards the Yellow Trail.  Eastern Towhee, Rose-breasted Grosbeak, Scarlet Tanager and Blue-winged Warblers can be found along this stretch and occasionally a Hooded Warbler or two.  A stretch of scrub just before the Yellow Trail can have White-eyed Vireo, Chestnut-sided Warblers, Blue-winged Warbler and Veery.  The Green Trail meets the Yellow Trail in the apex of its loop.  A small creek cuts across this loop and there are bridges over the creek a short distance from the trail intersection both to the left and right.  The area between these bridges has held Hooded and Kentucky Warblers and a Louisiana Waterthrush has been found near the two bridges for several years.  Taking the Yellow Trail north (left) takes you through more Hooded Warbler territory and those of other forest birds.  Going right (south and east) towards Swallow Cliff is good for more Hooded Warblers, Veery, Wood Thrush and Scarlet Tanagers.

Cap Sauers is one of the better areas in Cook County for Saw-whet, Eastern Screech, Great Horned and Barred Owls.  Pileated Woodpeckers have been observed or heard on the west (Green Trail) and north sides.  For Eastern Whip-poor-will, park on Ford Road after dark in Spring and early summer and walk east/right along the trail for ~100-200 yards and listen.

Green Oaks Field Station

Leave a comment

The premier location for breeding landbirds in Knox County, and an excellent birding location in general, is the Green Oaks Field Station.  The Field Station is owned and managed by Knox College as an area for research, conservation, education and recreation, and is generally open only to members of the Knox community (students, alumni, staff and faculty) and their accompanied guests.  Birders who would like to visit the site can contact Jim Mountjoy (jmountjoy@knox.edu) who would be happy to escort interested parties to Green Oaks, time permitting.

Green Oaks is over 700 acres in extent, most of which is forested (some of it mature growth with many centuries-old Eastern White Oaks).  There are also restored prairies, a strip mine lake, and several smaller ponds.  The entrance to the site is a gate on the east side of County Road 1800E, about 4.5 miles south of the town of Victoria.

The best areas for breeding birds are usually the mature forests and deep ravines, which are accessed by several trails.  The South Creek Trail and Locust Trail connect to form a loop of approximately two miles.  Along this route Acadian Flycatchers, Ovenbirds and Kentucky Warblers are usually easily found in season.  Pileated Woodpeckers and Red-shouldered Hawks are also regular, if somewhat less reliable.  Louisiana Waterthrushes and Northern Parulas are regular breeders, in small numbers.  Worm-eating and Cerulean Warblers have also bred here, although they may not be present every year.

The Little John Nature Trail is another area that may produce Louisiana Waterthrushes or Red-shouldered Hawks.  The edges of woodland and roadsides may be concentrate migrant songbirds in season.  The restored prairies have supported breeding Henslow’s Sparrows in some seasons.  Rarities observed at Green Oaks include Golden Eagle, Yellow Rail, Barn Owl and Bewick’s Wren.

Several other good birding areas are located in the area, including Snake Den Road to the south, the Oak Run/Spoon Lake area to the west, and the open country and strip mine lakes of the countryside north of Victoria.
