I believe I’ve mentioned before that we’ve lost two broods of ducklings in Botany Pond this year: Vashti’s brood of 7 and then an unnamed duck’s brood of 12. I was in Savannah, Georgia when Vashti’s brood came down on Sunday, April 19, and several people fed her and her brood, though of course the brood doesn’t each much at first because they’re still going on residual egg yolk. There was a storm, and then, on Tuesday, April 21, the brood vanished some time in the afternoon. We don’t know what happened, but I have a good idea based on watching the brood of the second duck (see below).
Here’s the only picture I have on hand of Vashti’s first brood, taken by a member of Team Duck with an iPhone. There were seven; I think one is out of range or behind her.
Nobody saw what happened but she was gone. On May 1, a hen returned to the pond, and she clearly knew me, coming for food on my whistle and consorting with Armon, her spouse, who had patiently abided in the pond the whole time. Bill photos (not shown) matched her with 100% accuracy to the Vashti who left. She’s shown below. As for what happened to the ducklings, well, it’s best not to think of it.
Below: Vashti returned! After about two weeks she re-nested, using exactly the same first-floor nest she had last time. But more on that in a later post.
That was it for a while, and then, on the afternoon of May 22, someone reported a lone duckling on the other side of the building from the pond side where Vashti had nested. I rescued it at great effort with the help of another Team Duck member; the rescue was hard as it ran into a tangle of vines and leaves at the bottom of an adjacent building, but we got it and I took it to the Chicago Bird Collision monitors for rescue, where it would be taken to rehab. It was clearly a newly-hatched duckling, as it still had its “egg tooth.”
Suspecting that it might have fallen out of a nest somewhere on that side of the building, I went back early next morning, and, sure enouogh, I found yet another newly-hatched duckling on the ground near the same spot. I took it upstairs and put it in a box with soft teeshirts near a space heater (they need to be kept warm). I was fairly sure by then that there was a nest up above on the non-pond side of the building, and, sure enough, when I went back, there was a mother duck with about five babies in tow, trying to get to the pond. The problem was that she was trying to go on the north side, which required going up stairs, across a breezeway, and then going down. The ducklings couldn’t jump that high, so I had to shoo the brood around the south side of the building, through the vegetation and a fence, and into the pond.
But wait! There’s more! After the unnamed hen (I’ll call her “UH”) was in the pond, I went back to the spot where I saw her, and, sure enough, there were six more babies milling about, peeping piteously, and looking for mom. Several got stuck in a window well. I got them all, put them in a fly net, and walked them back to the pond. Picking up two at a time, I put them on a rock in the pond. The mother heard their peeping and swam to them immediately. I did this three times until there were eleven ducklings with UH. Then I went back upstairs, got the early-morning straggler, and put it on the rock. Sure enough, UH came back and retrieved that one, too. Now, with mom and all twelve babies together in the pond, I was happy—and quite proud of myself of retrieving them in the morning all by myself (this was at about 6:30-7:30 a.m.).
Here they are (or rather, were). The mother started, as always, giving them the obligatory tour of the pond.
After the circumnavigation I was glad that Mom took them out of the water to dry off, sitting on a rock and then squatting on the ducklings to dry them off and oil them:
I sat on the benches nearby, for several drakes in the pond (I don’t think Armon was one of them) began harassing the brood; they wanted to mate with the mother. She would fly away and then return to the brood—over and over again. Sadly, the harassment continued, and I was there until about 11 a.m. when the mother, followed by her entire brood, walked south through the fence into dense vegetation.
That was the last time I saw them; I didn’t want to go tramping through the bushes and weeds lest I squash somebody or scare them. I was sure they’d return, but they didn’t. (Mom later came back, like Vashti did, and she’s still here, but so far didn’t renest.) Every day for four or five days I would scour the area around the pond, including adjacent buildings near the quad, looking for the brood, but they were gone. Like Vashti’s first brood, it is certain that all the ducklings perished. I was—and still am—heartbroken.
In the next post, which I’ll write in a day or two, I’ll relate how Vashti produced seven eggs, and how with the help of Facilities we devised a scheme to capture the whole family before they could get to the pond and be harassed out of existence. But more on that later. How about some brighter topics now?
Turtles are also a perennial favorite, and we have five red-eared sliders (or rather, four red-eared sliders and one yellow-bellied slider; all are members of two subspecies of the same species, the pond slider Trachemys scripta.) Here are some photos:
Here are all five sunning on a rock; only rarely do we see them all together like this. You can see that one has more melanin than the others; Greg Mayer, who has visited, calls it “Mel”:
More usually we see two, three, or four. Everybody who walks by them stops to look, and many people whip out their phones to take photos:
They are cold-blooded (“poikilothermic”), and so to warm up enough to swim and metabolize, they love to lie in the sun, stretching out their limbs and necks to expose as much of the blood-containing tissue as possible. We call this “turtle yoga”, and I always explain to people by the pond what is going on, as they don’t understand the stretching:
More turtle yoga. Look at those stretches!
Head shots:
But I don’t tend the turtles, save for tossing them an occasional pellet of duck food. I just make sure that nobody bothers them (and believe me, people try). With no ducks to play with, I engage with the three resident squirrels by the Pond, two of which are fairly tame and the other one skittish. The tame one will crawl up my pants to get a nut; I give them entire walnuts in the shell, and roasted unsalted peanuts in the shell (I have to worry about their blood pressure!). Here’s one who climbed on me while I was watching the ducks with binoculars (it’s early in the morning and I’m dishevelled):
The tamest one (I have not given them names):
Look at that adorable face:
That one has, besides being tame enough to know me and crawl up my body, finally allowed me to pet her, which is not something you want to do to a squirrel you don’t know. DO NOT TRY THIS AT HOME! I had to get her (it’s a lactating female) to get used to being touched and now I can gently place my hand on her back while she positions a nut in her mouth:
Saturday, June 6 was graduation day at the University of Chicago. By that time Vashti had been back nesting for about three weeks (I calculated that she began sitting on a new batch of eggs on May 15, but I was off a bit, as you’ll see in the subsequent post.
Entering the Quad from the street:
Marching to the Quad. I didn’t go to graduation, but I didn’t hear of any disruptions this year. Congrats to the grads; it’s a hard slog here!
More on Vashti’s second brood in the next post.


















That’s the true test of commitment – following through even when the going gets rough.

Wow. That’s quite the story of duck woe. Maybe the steps you’re taking with the upcoming brood will work. The stress is evident. Just imagine if you were responsible for endangered species!
My sincere condolences about the ducks.
I am happy that you may have come up with a plan with your facilities people to protect/rescue the next batch of ducklings.
Good job!
Wow. F those harassing drakes. I wonder if there has been a recent boom in the mallard population that accounts for the increased number of rapey drakes this year.
Any chance that the turtles will mate and lay eggs around the pond?
Brooke, the population explosion of drakes is purely endogenous I think.
Please don’t anthropomorphize them. Competitive aggressiveness is the trait that maximizes their own reproductive success. There is always a shortage of females because they’re choosy. When they have young to care for, they have other priorities, which the drakes have an interest in subverting because the ducklings aren’t theirs. We all know that, I think. The drakes and hens are just being ducks. A non-human male animal can no more commit rape than a male cherry tree can.
Absent a cull of the males, which is illegal out of hunting season, Jerry is doing the best he can to protect the brood(s).
And he is the Best Dad Duck EVER!
Chicago is a bit beyond the northern edge of the red-eared slider’s natural range. It’s likely that the climate there doesn’t allow sufficient degree-days for successful incubation of a clutch of eggs – turtles bury their eggs and rely upon environmental heat for incubation.
Not that this would necessarily stop the Botany Pond turtles, if there are both males and females and a place where females could successfully climb out and dig a nest. But the eggs would probably not complete development in time to hatch.
Yes, we’ve had nests but the eggs didn’t hatch. HOWEVER, the year before they dredged the pond somebody reproduced, as we had tiny baby turtles. They probably killed them all when they dredged the pond. Very sad.
My congratulations to the grads. It is a hard slog, yes. Doesn’t the bookstore sell hoodies with the legend, “UC. Where fun goes to die!”? I have fantasies of seeing my granddaughter marching in that procession, not that I would dream of being an interfering grandparent. Hey, ten years goes by fast and she’ll be graduating from high school.
One thing I enjoy about the photos of mallard hens is the reminder of that attractive blue flash, at the wingtip is it? It seems to vary between a deep sea blue and sky blue. It’s always a pleasant surprise to see it.
It’s on the wings and called a speculum. Nobody knows what it’s for.
My wife was at a conference in Chicago this week. I was bummed I couldn’t go with her (puppy duties) or you and I could have played about in Botany Pond. It looks so fun!
My favorites are the turtles.
Maybe you should black out the ducks’ faces on WEIT photos to protect their anonymity?
🙂
best,

If you think you know the route the ducks are taking to escape the drakes, could facilities permit the creation of a temporary system of waterholes the moms and broods can use on their journey? Maybe fill some small plastic wading pools with pond water and tuck them into bushy areas on the route. It’s a heartbreaking situation.
No, that would be a HUGE job, and we don’t know where the ducks go anyway. Nobody ever reported an errant brood this year.
Thank you. I wish there were more ways to save those babies.
I know this is probably over the word limit, but it is about ducks, so I hope you will excuse me.
I asked Gemini AI what will make drakes leave a pond and told it what happened to Vashti.
It replied….
While they are highly territorial during the spring breeding season, they will leave a pond for several reasons.
Here is what drives a drake to finally pack up and move on
:
1. The “Molt” Migration (Summer)
This is the most likely thing that will change his behavior soon. Right after the breeding season ends (usually between June and August), drakes undergo a “nuptial molt.” They lose all their bright, colorful feathers and grow a dull, female-like “eclipse” plumage.
• During this time, they completely lose their ability to fly for about 3 to 4 weeks.
• Because they are defenseless, drakes usually leave smaller, open neighborhood ponds and retreat to larger bodies of water with dense reeds and heavy cover to hide from predators.
2. Lack of Females
Drakes stay in a specific spot during the spring because they are looking for mating opportunities or guarding a mate. If all the female ducks have abandoned the pond, his biological drive to stay there drops significantly. Once he realizes there are no females left to pursue, he will likely fly off to look for a new flock.
3. Food Scarcity & Changing Seasons
Ducks are highly driven by resource availability. If neighbors stop feeding them, or if natural food sources (like algae, insects, and pond weeds) deplete as summer progresses, he will leave to find better foraging grounds.
Why is he acting so aggressively?
What you are seeing is a darker side of duck biology. After a female hatches her eggs, she completely isolates herself from the male to raise her ducklings. The drakes, still driven by high testosterone levels, become frustrated and aggressive. They will aggressively try to force un-mated females (and even mothers) to mate.
Because ducklings slow the mother down, aggressive drakes will often attack or ignore the babies entirely, forcing the mother to make a desperate run for safety. Unfortunately, traveling over land is incredibly dangerous for tiny ducklings, which is likely why they didn’t survive the move.
What you can do right now
If you want to encourage him to leave sooner rather than later:
• Stop all feeding: If anyone is feeding the ducks at this pond, ask them to stop. Removing the easy food supply is the fastest way to make a solitary, aggressive drake move on.
• Give it a few weeks: As summer transitions into the molting phase, his testosterone will plummet, his aggression will vanish, and he will likely seek out a safer, larger body of water.
It doesn’t sound like there’s much that can be done. I hope the little thug doesn’t come back again next year.
