Birds poured into St. James Farm Forest Preserve in mid-May as the wave crest of neotropical migrants pushed through northern Illinois. On some days, sorting through the many songs to note visiting species was a challenge.
Not all were singing, though, for example this bald eagle that stopped in the restored stream corridor.
Blue-gray gnatcatchers are common on the preserve, and are among the earliest nesters.
I am hoping this hooded warbler, singing among the thicketed portions of the central forest, will find a mate and nest there.
I took that photo from a distance on a foggy day, not wanting to get too close and create a disturbance.
This sharp-shinned hawk was very vocal, its calls to my ear less like those of its relative the Cooper’s hawk and more like those of a shorebird.
At one point, heavy rains flooded the stream well beyond its banks.
The engineered restoration corridor held up well to the challenge.
Among the water-loving birds that took advantage of this temporary habitat expansion was a double-crested cormorant, here taking a break between swims.
After the water receded, the deposited mud interested a few late shorebird migrants, including this least sandpiper.
For other birds, the breeding season is well under way.
I am not sure where this goose brood came from, but they have found the restored stream corridor to their liking.
Among my happiest observations in the second half of May has been the discovery of two eastern bluebird nests in natural cavities.
Here the male stuffs food into unseen nestlings in a bur oak cavity.
Mom takes her turn. In just a few minutes I saw each parent make 3 such feeding trips.
The same story was repeated in a dead tree near the stream. I am relieved that not all bluebirds are dependent upon human-provided nest boxes.
A little earlier in their own cycle, a pair of red-headed woodpeckers has been setting up shop in another dead tree.
They have settled upon the lower of the two holes beside the foreground bird. (Clicking on any photo will blow it up for better viewing).
This pair energetically repelled another pair which expressed interest in their tree. I hope the other pair also will nest at St. James Farm.
