Black-Crowned Night Herons Thriving

Last winter the Chicago Park District, after consulting with the Illinois Department of Natural Resources and the Urban Wildlife Institute, made the very difficult decision to remove a number of trees south of Nature Boardwalk in Lincoln Park. Many of these trees were ash that suffered terrible damage at the hands (well, actually mouths) of the emerald ash borer beetle, and became safety concerns.

It’s Baby Season: Enjoy from a Distance!

Spring is baby season, and with babies come protective parents. At Nature Boardwalk at Lincoln Park Zoo, we’ve seen some Canada goose goslings and mallard ducklings scooting around the pond of late, typically under the watchful eye of a parent.

With mallards, the mother looks after the ducklings while they grow and learn how to make it on their own.

It’s been about six weeks since the first black-crowned night herons arrived at Lincoln Park. At first, the herons seemed to hang out primarily on the island in the pond at Nature Boardwalk at Lincoln Park Zoo.

Painted Turtles Are Out and About

The sun is finally out! The painted turtles at Nature Boardwalk at Lincoln Park Zoo have certainly noticed; many turtles have been basking around the island on rocks or logs this week.

Some of the pond’s turtles are equipped with radio transmitters that allow biologists at the zoo to track their movement throughout the pond. This lets us better understand how the turtles use the site.

Warblers Galore

In the last few weeks, we’ve observed an influx of all types of warblers at Nature Boardwalk at Lincoln Park Zoo. Warblers are small insect-eating birds that, as the name implies, are also acclaimed vocalists. They have narrow, very pointy beaks, like tiny tweezers.

The warblers are passing through the site on their migratory route, which helps explain the sudden increase in abundance and diversity.

Brand New Butterfly

This little, rather nondescript insect was seen laboriously making its way along the path at Nature Boardwalk at Lincoln Park Zoo. Upon closer inspection, it was revealed to be a cabbage white butterfly, newly emerged from its chrysalis.

Swallows Swooping at Nature Boardwalk

As temperatures rise and flying insects become more abundant, insect-eating birds become more common as well. One such group of birds is swallows, and lately we’ve been seeing lots of them at Nature Boardwalk at Lincoln Park Zoo.

A group of swallows is called a flight. This name is appropriate, as these birds are constantly in flight, never seeming to rest even for an instant.

Kings of the Boardwalk

“Royalty” has been gracing us with its presence at Nature Boardwalk at Lincoln Park Zoo of late. Here’s what to look for to spot kingfishers and kinglets:

Belted Kingfisher: In many bird species, the males are more colorful than the females. Some species, such as red-winged blackbirds or wood ducks, take the difference to extremes. However, belted kingfishers buck the trend; females are more colorful than males!

Creepers Creeping at Nature Boardwalk

Brown creepers are small birds with long tails that creep up tree trunks when foraging. We’ve been seeing these birds at Nature Boardwalk the last few days, scaling some of the larger trees at the site, spiraling upward.

When they do this, they are looking in the crevices and under the bark for any insects or larva they might be able to pry out and eat.

Black-Crowned Night Herons Are Back

These four black-crowned night herons represent our first sighting of the species this season at Nature Boardwalk at Lincoln Park Zoo. Pictured in trees on the island on March 30, they’re most likely the birds that completed their migration fastest, the trailblazers.

Last year, Nature Boardwalk’s black-crowned night heron breeding colony contained more than 200 adults at the peak of breeding season.

Eastern Phoebe (aka Tail-Wagging Hovercrafts)

If you know what to look for, it’s hard to mistake an eastern phoebe for anything else. First, phoebes say their name in their call! Second, the bird isn’t shy, often sitting on fence posts or tall prairie plant stems at Nature Boardwalk at Lincoln Park Zoo, wagging its tail up and down.

Beyond that, the eastern phoebe is one of several amazing birds that hover in flight when foraging.
