Baby Birds and their Parents, 2017

2017 was another great summer for nesting birds at Douglas Park! More than 20 kinds of birds raised their babies in the park. A half dozen other bird species captured food in the park and took it to their babies in far-off nests. Now those mostly-grown babies (like herons and gulls) have come to Douglas Park to find their own food

The photos below show baby birds in their nests (nestlings), birds that have just left their nests (fledglings), and birds that have their own special baby names (ducklings and goslings). There are also photos of parent birds singing near their nests, feeding their babies, and protecting their young.

Monarch Butterflies in Douglas Park, 2017

We saw lots of Monarch butterflies in Douglas Park druing the summer and early fall of 2017!

During June and July, we often saw Monarchs sipping nectar on milkweed flowers, especially on Swamp Milkweed that grows at the edges of the lagoons. These Monarchs probably laid their eggs on the park’s milkweed plants. During August and September, we saw Monarchs fueling up on nectar from many other kinds of wildflowers. These later Monarchs were probably migrating south to Mexico.

Here are some photos of Monarch butterflies on wildflowers, taken during 2017 in Douglas Park:

According to the following DNAInfo article, many other Chicago area residents reported seeing more Monarchs during the summer of 2017:  Monarch Butterflies Flying High This Year After Recent Declines





Summer Wildflowers 2017

We found lots of wildflowers in Douglas Park’s Bird and Butterfly Sanctuary during the summer of 2017! This slide show includes many of the wildflowers that have bloomed that summer in the park’s meadow and prairie habitats.

These photos were taken from early June through the first few days of August, 2017. The photos include a mix of wildflowers that grew in Chicago before it became a city and flowers that originated elsewhere in the world.

If you want to explore Douglas Park’s wildflowers on your own, this guide from the Field Museum will help you identify them:

Breeding Birds of 2017: Pied-billed Grebes

Pied-billed Grebes successfully reared their young on the Bird and Butterfly Sanctuary lagoon last summer. All through this spring we wondered, could they do it again?


By early April there were two Pied-billed Grebes hanging out together on the sanctuary lagoon. (April 8, 2017)


But after mid April we only saw one grebe, always alone. We sometimes heard it sing, but we were concerned that we never saw a second grebe. (April 17, 2017)


Then in mid May we saw an encouraging sign. The lone Pied-billed Grebe approached a small flock of Hooded Mergansers…..


…and then attacked, chasing them off! Male Pied-billed Grebes defend their territories against both other grebes and ducks of all kinds. So maybe this grebe was on territory, and its mate was on a nest hidden somewhere in the reeds and cattails. (May 16, 2017)


But then, for more a month, we saw only one grebe on the lagoon. It sang most days we visited the park, but we wondered what was happening with its mate. (May 29, 2017)


Finally, on June 18, we saw the mother grebe with eight half-grown young!  She must have kept her brood hidden in the reeds for several weeks, at least when we were in the park. (June 18. 2017)


The mother grebe was still a bit shy with her young. As soon as she saw us, she had them line up behind her and follow her back into the reeds. We did not see them again for the rest of the day. (June 18, 2017).


For the next few weeks we saw the grebe family during each of our visits to the park. Usually they stayed far out on the lagoon, with the mom staying close to the young grebes. (June 26, 2017)


The mother grebe caught small catfish to feed her young ones….


,,,passing the fish to the young grebes and then swimming nearby to make sure everything went well.


This time, the catfish proved a challenge for the young grebe. The fish was dropped at least three times, but each time the mother re-caught the catfish and passed it back to the young grebe….


…until finally the fish was successfully swallowed! (July 11, 2017)


By the second week in July, some of the young grebes were already catching and swallowing small catfish on their own. So it looks like the parent grebes have had another successful year raising young on the sanctuary lagoon! (July 11, 2017)

Breeding Birds of 2017: Cooper’s Hawks

More than 20 kinds of birds have been raising their young in Douglas Park during the spring and summer of 2017.  Here’s a photo report on one species: Cooper’s Hawks.

This year Cooper’s Hawks nested across Sacramento Avenue from the Bird and Butterfly Sanctuary. I was able to follow the progress of the Cooper’s Hawk nest from early March, while the nest was still being built, through July, when both of the young hawks were out of the nest.


The Cooper’s Hawk nest was build high in a honey locust tree on the west side of Sacramento Avenue. (March 5, 2017)


The parents were still adding sticks to the nest in early March. (March 5, 2017)


The eggs were laid by mid April, and we could see the mother hawk keeping them warm. Sometimes we just saw her head. (April 25, 2017).


Sometimes we could just see the mother’s tail and wing tips. (May 16, 2017)


The eggs had hatched by late May, and we had our first peeks at the downy white young (the small white patch to the left of the mother). (May 29, 2017)


By early June the mother was defending her nestlings when we got too close. (June 4, 2017)


By mid June the young hawks were ready to emerge from the nest. (June 18, 2017)


The young hawks tried out their wings, flying to nearby branches. (June 18, 2017)


In late June, one of the young hawks was still at the nest, The other young hawk had moved elsewhere. (June 26, 2017)


In early July, one of the young hawks was still near the nest, waiting for a parent to arrive with a meal. (July 3, 2017)
