Breaking: Volunteers on my team report that box #77 fledged yesterday (which would imply hatch on Tuesday, 19 April). The hen and 12 Hooded Merganser ducklings (the complete clutch) exited the box. Smiles all around.

More surprises in this week’s report:
Lots of activity in the boxes and outside, but no new hatches. We have a new clutch started in box #10, and we found 1 in in box #5 that might be the start of a clutch. That brings the total of boxes with eggs to 15 out of 16 (9 Wood Duck, 6 Hooded Merganser), which is unusually high; but it’s not clear that box #13 will be incubated. We saw a group of 7 small Hooded Merganser ducklings and hen in the new pool by the tower, so that group must have come from a natural cavity.
Several boxes were due, or almost due, on Sunday, but did not hatch, so we will have a lot of boxes to check next time.

Our next work day will be Sunday, 1 May. Much thanks!

- Bird-friendly coffee is also pollinator-friendly and good for the farmer, too, according to new research from Alejandra Martínez-Salinas et al.
- Jennifer Vanasco’s story about playback of long-unheard mystery wax cylinders buries the lede, in my humble option. The Endpoint Cylinder and Dictabelt Machine also plays back dictabelts, such as would have been used by Sid Sorokin.
- Annie Lindsay and fellow bird banders at Powdermill Avian Research Center devised an air compressor adapted to be a blower for bird feathers. Gently blowing on a bird’s body plumage exposes how much fat the bird is carrying, and is sometimes used for other measurements. Using the machine in preference to the traditional technique (the bander’s own breath) means that COVID-19 prevention protocols can remain in place.

First report for April:
First hatch! Box #7 hatched out. Photographers reported ducklings leaving the box at about 8:30 Sunday morning; estimate was 14 ducklings. I revised some of the previous notes. Box #7 must have been the box that was already started on 27 February.
Meanwhile, box #6 continues to incubate, along with several others. Box #4 has turned into a dump nest, with 24 eggs. Let’s hope for the best.
I had planned to patch the roof of #67, but a drake was standing guard atop the box, so I will postpone maintenance work until this box hatches.
Does anyone have notes for box #13?

Danke schoen!

The weekly report:
And still more new nests! We have 12 boxes with at least one egg.
I repainted the number on #67, but my plywood patch on the roof has flaked off. The foam crack filler is still holding. Let’s hope for the best, because we have a Wood Duck incubating in this box.
Also new nests in #3 and #4, and a couple boxes with one or two eggs.
Box #6 may be ready to hatch by next Sunday.

Weather cooperating, we’ll work 3 April, 17 April, and 1 May.
Merci beaucoup!
On the way to Pirsig Avenue
The houses along Maple were a free-for-all of competitive decoration, their shrubbery and railings and rooflines infested with green plastic vines bearing fruits in dull colors. It wasn’t clear to Marion that the charm of Christmas lights at night was enough to offset how ugly the hardware looked in daylight hours, of which there were many. Nor was it clear that the excitement of Christmas for children was enough to make up for the disenchanted drudgery of it in their adult years, of which there were likewise many.

Just take the dang picture
“Have iPhone Cameras Become Too Smart?,” by Kyle Chayka. I really want to quote the whole piece as a blockquote, but I will just pull out:
We are all pro photographers now, at the tap of a finger, but that doesn’t mean our photos are good.

A much warmer and more successful morning.
More nests started, and five are incubating! Eight boxes are active. Our first Wood Duck box is #1, in the pool by the tower.
We repaired the hardware cloth on box #68. Access to #84 remains a problem: as mounted, the lid won’t open sufficiently. Next week we plan to repaint the number for box #67 and clean up trash around the tower.
Some splashes of Spring Beauty, with most buds tightly closed in the mid-morning.
Until next week! Arigatoo!

Small disaster. Last week’s cold snap and snow left the ponds iced over on Sunday. Ordinarily, we can break through the ice with our sticks, but the ice was just thick enough that instead, I tried following C’s footsteps out to box #2, the first box off the boardwalk— walking in an area that I didn’t know very well. Almost immediately, I lost my balance and caught some serious mud from the wetland. As a result, we cut the work day short. We’ll get ’em next week.
Fortunately, I had my chest waders on. My jacket got the worst of it.

After 40 years of work, Guinea worm disease is nearing eradication, but we’re not there yet. A reservoir in other animals is a hindrance to getting rid of it entirely.
Ephemeroptera
Neonics aren’t just bad for pollinators. As Shauna Stephenson reports, aquatic invertebrates are also adversely affected, which is bad news for fish.

Oh, a very much useful annotation unearthed by M. Paul Shore: recte.
For the last four-and-a-half decades of my life, from late teens to early sixties, I’ve had the nagging feeling that there ought to be a Latin scholarly expression that one could use when presenting the correction of an erroneous word or words in quoted material alongside the error itself.

Another Sunday’s report:
Nests continue to develop. Box #68 added 7 eggs, just as if the hen was reading the calendar. My notes say that we have 4 eggs in #7 and 4 eggs in #77 — I will double check. And the 14 eggs in #6 are now incubating. It’s a little difficult to get a good count for this box.
We screwed together boxes #7 and #77. We also tried to adjust box #84, but in the process, the pole snapped off. It had rusted at the former waterline. So we did what we could, but the box is now low to the ground and a little wobbly.
K and C will leave some hardware cloth in the shed so that we can patch the duckling ladder in box #68.
I was responding to a query from a Friend of Little Hunting Creek: that group is looking to install some nest boxes, and I was sharing some of our experiences. And I realized that I didn’t have a previous blog post to direct them to on the subject of raccoon-resistant box closures. In fact, I couldn’t remember the name of one of the pieces of hardware that we use. So let’s rectify that missing information.
In some cases, a hook-and-eye on a spring has been sufficient.
For the more tenacious critters, we’ve gone to a hasp closed with a quick link. Links come in various sizes, so make sure you have one to fit the hasp. The link looks something like a carabiner, but it doesn’t squeeze open. Rather, you have to twist the hexagonal part. After a few years in the elements, you will need to give the link a bit of lubricating oil.
