Update: the Dorm Ducks

July 14, 2023 • 1:15 pm

We are feeding and watering the eleven “dorm ducks” (Maria and her ten babies) three times a week, and they’re growing like weeds. But I tell you, it’s a big job, as we have to cart all the food and water three blocks from my lab (there’s no hose). But our reward is that there are still ten babies (well, adolescents) and they look terrific!  MAH-VELOUS, in fact! Click the pictures to enlarge them.

Here are some pictures and videos. Thanks to the other two members of Team Duck, Gracemary and Marie, for their constant help.

First, Maria and her babies. She has a spectacular speculum (the flash of blue feathers on her side). They love the rain, as they can splash around in the puddles and hunker down with their bellies in the water. If there were a hose on the plaza it would be a lot easier, but all the irrigation is drip irrigation, so we need to cart over about ten gallons of water (along with duckling chow and mealworms) each visit: M, W, F.

The brood: ten—count them—ten!

A panorama of one side of the plaza with food and water. We have the same setup on the other side:

They like to crowd into water to have a bath and a drink. Here’s the first of two videos.

The lovely Maria. A great mom!

This is a bill identification picture in case she should return next year. We don’t want her to nest there, though!

A watchful mom:

We gave them frozen defrosted corn; they loved it!

Marie looking up; I think a bird flew over, but it wasn’t a raptor:

A lucky duckling gets its own tub, and then exits for a feed, followed by its littermates. They get only the best food: Mazuri Waterfowl Starter Chow (they’ll soon graduate to Duck Maintenance Chow) and freeze-dried mealworms, which they love.

The lucky duck:

Rub-a-dub-dub, seven ducks in a tub. We now have a bigger basin for them to swim in, and will increase the size of their “pool” as they get bigger (they have to be able to get in and out):

Wish us luck. If any U of C people are reading and want to volunteer to help, please get in touch with me.

And to think that I was looking forward to a duck-free summer!

Today is Sunday, ergo John Avise is here with a particularly winsome batch of baby birds, including two species of DUCKS.  John’s captions are indented, and you can enlarge the photos by clicking on them.

Baby Birds 

Depending on the species, avian babies come in several types ranging between two extremes: precocial and altricial.  Precocial chicks typically hatch with a full set of downy feathers and quickly leave the nest to feed and fend for themselves (often with parental guidance).  By contrast, altricial young hatch nearly naked and helpless, and require intensive care and feeding by their parents until they grow more feathers and eventually fledge.  Precocial babies can be very cute, whereas altricial babies often tend to be– well, rather ugly.  This week’s post shows several examples of cute and not-so-cute avian babies and other youngsters.

Our haul today

July 8, 2023 • 12:45 pm

Nine new ducklings: Amy the Library Duck’s entire brood. Believe me, we tried to get Amy and her brood to the nearest water (1.5 miles away), putting the ducklings in a padded but clear box so she could see them, and then walking towards the lake. She followed for less than half a block before flying away back to the nest.  And she was not leading them on their own to the water.  Nor would she let us get near her to catch her. (Catching adult mallards has always been impossible for Team Duck.)

After some futile attempts to catch the mother, who put on the first broken-wing display I’ve ever seen in a mallard, we gave up and took all nine (healthy and strong) babies to the rehab person.  This always breaks my heart, but it’s better than letting all the ducklings die.  We had three plans worked out but, as I suspected, we wound up, in the end, taking the ducklings to rehab—plan C.

Here’s our haul from this morning. (Please don’t ask me about alternative plans; we’ve thought of them all and had six people there dealing with the issue.)

BUT we are still tending a mother and her ten offspring on the plaza between two dorms, as the babies cannot escape until they can fly. (There’s a large fence.)  Here are Maria and her babies, whom we tend three times a week.  Note that these are older—probably at least two weeks old.

I’ll have a longer post about this in a few days—after I’ve recovered.

The patio ducks

July 4, 2023 • 9:30 am

As I noted about a week ago, a mother mallard has had ten babies on a second-floor plaza connecting two dorms at my University.  It’s a nice secluded space, large and complete with a cement sitting area and plenty of grass and tree.  But there is no way the babies could have jumped to the ground and found their way to water, as the plaza is ringed by an insurmountable wall.

Last year, when a hen nested and had a brood there, the only way I could think of to save them was to remove the babies from the mother soon after they hatched and take them to rehab. I did that, but when I lifted Mom off the nest and scooped up her babies, she went nuts, quacking and following me around as I carried the box out of the dorm. It broke my heart, and I still get quite upset thinking about it; but at the time it was the only way I knew how to save them. There was no way they could get to water, and I wouldn’t be allowed in the dorm regularly to tend the brood.

It turns out that mom re-nested there and had a second brood. Apparently the summer-school students decided to tend them, giving them food, water, and even a kiddy swimming pool, and, as far as I know, the babies survived, did well, and fledged.  (I didn’t get to see that but only heard about it.)

This year Mom did it again (I’m not sure it’s the same mother!), and a brood of ten appeared from a hen whom we’ve named Maria.  But this year there are no students in the dorm during the summer. The tending, therefore, falls to us.

What to do? Fortunately, the people at Facilities called me, knowing that I was the Duck Whisperer, and asked for help. I and several members of Team Duck went up to the plaza to have a look-see. Sure enough, there was a protective mom with ten four- or five-day-old babies. This time we decided not to separate mom and babies, but to go to the dorm at regular intervals and give them all food, water, and swimming facilities. That is a LOT of work, as we have to schlep food and water over there and clean out all the food and water dishes each time. (There is no hose, so all water is either brought over or taken from a very slow-runnibng bathroom sink.) But, being a hard determinist, I realize that I have no choice in this matter.  I must follow my motto, ‘no duckling left behind.”

And so Facilities has allowed us to visit them every couple of days to fill up the food and water bowls, and install swimming facilities.  We had one of our visits yesterday, and here are some photos.

A sign on the door to the plaza put there by Facilities. They are taking this matter seriously, which pleases me:

And an ironic sign on the outside wall:

Below, the layout: this is a second-floor plaza between two dorms (one on the right), and you can see that it’s large, isolated (and undisturbed in the absence of students), and has plenty of grass, trees, and bushes. Two members of Team Duck are enjoying the scenery. (This was several days ago when the ducks were hiding in the bushes to the right. Now they are used to our presence as we don’t approach them, and they know that our appearance means food and water.

We have put food and water dishes, as well as swimming tubs, along the wall that separates the patio from the grass. (You can see them at the base of the wall.) There’s a similar wall with dishes behind the photographer (me).

Maria and her brood. Yes, there are ten—count them—ten. A head count is the first thing we do each visit. She is a terrific mother, always standing guard over the brood. Note the small duck pellets we gave them to entice them toward the food bowls. (It worked.) The pellets are Mazuri Waterfowl Starter Chow—the best duckling food money can buy, and a complete diet. (We supplement it with dried mealworms.)

When it’s hot, as it was yesterday, the ducklings like the shade under the chairs, but I’m sure that when we’re gone they also go into the shrubbery. Note Maria standing by:

The ducklings have gotten bigger in just a week.  Here they are with their food and water bowls, as well as the big water-filled containers that serve for the nonce as swimming (or rather, splashing) facilities. This week we are going to put in much larger tubs in which they can all really swim, but we want to first ensure that they’ll be able to get in and out of them.  Right now there are four places to immerse themselves and splash, while the food and water dishes are to the side:

Maria may have seen a predator above, as she’s looking up, along with some of the babies:

We aren’t allowed a lot of time with the patio ducks, and so I couldn’t take many pictures. But as you see from their condition and full crops, they’re doing quite well.  Tomorrow we’ll go over again and take care of them, perhaps bringing the “swimming pool” (a medium-sized cement-mixing vessel from Home Depot). When they get bigger we also have a larger one for them. Fingers crossed!

And Amy the library duck is scheduled to hatch her brood in about a week. Now THAT is going to be more trouble, as they can jump to the ground from the window. What to do then? Normally I’d herd them to Botany Pond, but there’s no water in it this summer. I either have to catch the babies and get them to rehab, or put them in a box and try to walk them, with mother following, the 1.5 miles to the nearest big pond.  That is unlikely to work, but we’ll first try to keep Amy and her babies together.

After a very rough Duck Year last summer, highlighted by the depredations of Audrey the Killer duck, who would allow no other broods in Botany Pond, as well as my repeated entry into the water to save 31 ducklings who would otherwise have been killed (resulting in multiple injuries to me as well as a few bouts of swimmer’s itch), I had hoped for a summer’s respite. No such luck. But at least I don’t have to jump into Botany Pond this year!

Our dorm ducks

June 27, 2023 • 12:45 pm

Yes, a mother and ten ducklings are marooned on the garden plaza connecting two dorms here, and I was called as the Duck Rescuer to deal with them. Our plan is to let them grow up on the plaza, as there’s plenty of space, shrubbery and lawns, as well as a cement area, and we will ensure that they’re fed and watered until they’re able to fly (they cannot jump off the plaza as it’s surrounded by a high wall). There are no students here, so there’s nobody to disturb them. Facilities and a kindly worker in the dorm are looking after them when I can’t get in—which is most of the time.

So, meet Maria and her ten ducklings (there were ten when I first saw them, so none have disappeared). “Maria” was the name of the grandmother of the woman at Facilities who alerted us to the brood and is helping us,

As a duck rescuer once told me, “Ducks are really good at finding safe places to nest, but not so good at finding safe places to nest near water.”  This is the case here, but we’re giving the babies plenty of water to splash around in.

Ten—count them—ten.

Ceiling Cat help me—I do love my ducks!

And they’re in very good shape. Look at those full crops!

Of course Amy is still incubating her brood on a Regenstein Library window ledge, and we’ll have to figure out how to deal with the hatchlings when they jump to the ground to be with mom.

Ducks upon ducks

June 23, 2023 • 1:20 pm

This morning two members of Team Duck went to look at the report of ten young ducklings on a dorm roof (actually, a big landscaped yard) where they can’t get out. We took a look, gave them tons of food and water, and decided to keep the babies with mom until they can fly. This, of course, involves a nearly daily schlep across campus and a labyrinthine trek through dorm basements to get to the garden. But I’ve just ordered another 25 pounds of baby duck food, and I have a big supply already on hand.

We couldn’t find any ducklings when we first walked onto the roof garden, but Marie heard peeping and there they were: ten adorable babies, probably 4-5 days old, all huddled together. Where was Mom? We were worried, but in a minute or so Mom appeared with loud quacking. She called to her babies, who ran to her.

By that time we’d placed bowls of duckling food and pans of water around the plaza, but they didn’t know what they were. So I tossed a handful of the small pellets to Mom, and it wasn’t long before she realized they were food, and began gobbling them up. The babies followed suit.

Mom discovers that what I was tossing her was good to eat!

And the babies tucked in, too:

We had a couple of little swimming pool pans, and when the ducklings saw them, and one jumped in, they all followed–all ten. I believe this is the first time they ever were immersed in water, and they were splashing with joy and drinking. (We’ll give them more pools by Monday.  I don’t even think they saw water until yesterday, when the boss at Facilities left out a bowl.

Now we’ll look after them until they’re ready to fly: in about 5-6 weeks. I didn’t expect to be doing such things this summer, but somebody has to. And it’s good to see ducklings again.

CHILDRENS’ SWIM TIME!

Amy the library duck

June 23, 2023 • 8:55 am

My hopes for a mallard-free year have been cruelly dashed. As I noted the other day, I rescued eight newborn ducklings that were wandering around campus with a mother who was leading them about aimlessly (they never would have gotten to water). Those are now at Willowbrook and will be brought up with care.

I received a call the other day, which I’ve also recounted, that a hen had nested on a windowsill at Regenstein Library—the main campus library—and the people there had named her Amy. She’s sitting on eggs, and we estimate a hatch date of about July 10. I suggested that they put a tub of water on the ground near the nest for when Amy wanted a drink or a bath (they leave the nest for an hour about every five days to tank up and wash off), and they did it immediately. They love her! Here’s the tub (it’s now full to the brim with water):

The window where she’s sitting has a webcam with chairs in front of it so people don’t disturb her. Here’s a photo of Amy burrowed down in her nest, probably to both avoid the heat and camouflage herself and her nest. (The window is dirty, but you can see her head at lower right plus the patterns on her feathers.)

They have put contact information for me next to the window in case people need duck help. I redacted that information.  You can see that the library people love her; this is what happens when a duck nests on your windowsill:

Finally, the live duck cam focused on Amy and her nest, which operates 24/7, is here, and you can also access it by clicking on the screenshot below, taken just a few minutes ago. Make sure when you go to the site that the video is turned on (i.e., you see a little triangle in the lower left corner).

And remember, ledge-nesting is a novel behavior in mallards. In the wild they nest on the ground, but as they’ve moved into urban areas, they’ve discovered that some window ledges, not accessible to ground predators, make ideal nest sites.

After checking on Amy yesterday, I got a call from Facilities that there’s a family of ten ducklings marooned on a dorm roof. It’s the same roof as last year, and I did one rescue/rehab there but the female re-nested right after that and managed to raise a second brood on the grassy roof (there are trees, too). I am bringing them food and water this morning, and checking on the situation. If mom is there, I’ll make sure they have food and water for the six weeks it’ll take for them to be able to fly.

No rest for the weary!
