Reverse Migration

Here in Illinois the offspring of the local Bald Eagles have just fledged. During the next 4-6 weeks they are expected to begin following their parents on fishing and hunting forays. By the time the cold weather arrives their proficiency should have improved to the point that they will strike out on their own. Depending upon the severity of the winter, they may move southward, joined by many more of their kind from the far northern reaches of the species' range, following along the Fox River to find open water, with many congregating downstream along the Illinois River to its confluence with the Mississippi River system.  

On May 18, one of the two eaglets was in the nest. It may have already fledged, but it is common for them return to the nest to be fed:

The Bald Eagles that nested near our Florida home did not breed successfully this year. If they had, their young would just now be polishing their hunting skills in preparation for a migration in the opposite direction. As temperatures increase in the waters of Florida lakes, fish seek the cooler depths. Young eagles find it easier to see and catch fish in the cooler lakes and rivers to the north. Many move up the east coast to the Carolinas and the Chesapeake Bay area, and some have been tracked into the extreme northeastern US.

You may recall that the original male of the the pair lost his mate in late October, 2014, and found a new companion in early December. Although they mated, their union did not produce any young. They seem to have bonded very well. Curiously, they both continue to work on the nest, adding and rearranging sticks.

We also are now heading the wrong way, flying back from Illinois to Florida, at least for a while, leaving what is left of the spring songbird migration behind us. Bad weather and lots of local travel and family events curtailed our time afield. Here are some photographic highlights of our stay in NE Illinois.

At Nelson Lake/Dick Young Marsh Forest Preserve in nearby Batavia, the grass had turned green and the trees were leafing out by the  middle of May:

A notable sighting at Nelson Lake on May 9 was a single Bobolink, the first reported in the county this season:

Bobolink 20150409

Bobolinks seem to have their plumage arranged the wrong way, as the undersides of most birds are lighter than their uppers. Posing on a fence post, the Bobolink demonstrates this feature very nicely:

Yellow-rumped Warblers, early arrivals, were still moving through the treetops:

Common Yellowthroats are already staking out nesting territories on the prairie:

American Goldfinches, befitting their name, have molted into their brilliant breeding (alternate) plumage:

Yellow Warblers offer a more subtle but no less beautiful shade:

I find it easy to overdose on Yellow Warbler photos:

This first year male Orchard Oriole will take on a brick-red coat by next season:

An Eastern Meadowlark sings enthusiastically:

A tad of yellow highlights the brow of a Savannah Sparrow:

While not sporting feathers, this early Eastern Tiger Swallowtail fits the theme as it probes the dandelions for nectar:

Indigo Buntings represent another primary color:

The clouds part momentarily, to allow a "blue-on-blue" portrait:

A Blue-gray Gnatcatcher incubates eggs in its expansible globular nest, fastened securely with spider webs and decorated with lichens:

One of my most sought-after spring arrivals, a Scarlet Tanager some distance away, completes the color wheel:

A Northern Cardinal also represents the red faction...

The older of our two Illinois granddaughters helps me spot orioles in the trees along the path at Hawk's Bluff Park in Batavia:

She points out a moth she found on the car window, unwittingly giving me my only image of a reflection:

The moth is a Hydriomena species, thanks to ID by Facebook friends:

To her delight, we get good looks at several Baltimore Orioles:

It is a bit surprising that I have not yet run out of my favorites for our Illinois stay, such as this Great Blue Heron on the shoals of the Fox River...

Spring migration is underway

We endured a wet and windy two weeks in Chicagoland until weather conditions changed to favor northbound migrants. Finally, the clouds disappeared, and we visited Nelson Lake/Dick Young Marsh Forest Preserve in Batavia. However, the northerly wind gusts of up to 40 miles per hour nearly knocked us over and drove the birds into hiding. The trees had not yet leafed out as we walked to the observation platform at the edge of the lake, on April 28:

 Although winds abated for a while, the next day we had similarly bad luck along the shores of the Fox River at Lippold Park:

While waiting for the sunshine, we did take advantage of breaks in the rain to visit the Bald Eagle nest only about a mile from our second home. This is the second nest that they have occupied, both on the grounds of the Mooseheart residential school. The first nest, initially occupied in 2005, collapsed in 2013 before the two eaglets were ready for flight. An attempt to replace the nest with a platform in an adjacent tree was not accepted and the young birds grounded themselves for a second time. They were captured and successfully rehabilitated.

Here they are at the first nest in June, 2010:

Our two Illinois granddaughters observed the first nest, back in 2012:

The next year the pair relocated and successfully raised three eaglets:

The nest tree is in the center of a paved parking lot (taken May 24, 2014 -- note the green foliage):

This year they were reported to have three young, but so far I could see only one. I am concerned about the apparent declining health of the nest tree, here photographed on April 27, 2015:

One of the adults feeds an eaglet:

By May 7, the eldest of the three owlets at Fabyan Park in Geneva had fledged, and the larger of its two younger siblings seemed almost ready to fly:

I did not obtain a good view of the oldest owl, high in an adjacent oak tree:

One of the parents roosted just under the newly fledged youngster:

At Hickory Knolls nature center in St. Charles, a male Eastern Bluebird rested on a nest box:

At Bliss Woods Nature Preserve in Sugar Mound, a pair of Blue-gray Gnatcatchers were busily constructing the foundation of their spherical nest of lichens and spider silk:

Color has returned to the preserve, notably...
