THE NEST BOX, NUMBER 27, FALL 2010
Wednesday, August 10th, 2011Club News
So, where were we? Ah yes, the last newsletter went out way back in March, just before our Annual General Meeting. The big item on the AGM agenda, as usual, was the election. And, also as usual, no revolutionaries stormed the battlements to throw the bums out, so all officers and directors were re-elected. President-for-life Bill Bower didn’t even have to prorogue the meeting to keep his job.
Among the reports presented at the AGM was Barc Dowden’s last bluebird report. After many years of looking after the club’s bluebird boxes in Bells Corners and sending reports annually to the Ontario Eastern Bluebird Society, Barc has decided it’s time to pass the torch. Tony and Gretchen Denton have graciously taken over the task. Bill thanked Barc, on behalf of the club, for all his work over the years. We offer him best wishes for the future.
Speaking of the Dentons, congratulations are due to them for winning the Ottawa Field Naturalists Club’s George McGee Service Award this year “for their long-standing dedicated work at the Fletcher Wildlife Garden.”
Special thank you
Bill thinks, and I agree, that it’s high time we said thank you to Scott Smithers and the rest of the Ministry of Natural Resources staff in Kemptville for their on-going assistance in providing us with funds (CFWIP Grants) for our wood duck nest box construction projects.
Memberships
We have two new members to welcome to the club — Dr. Charles Murray joined in April and Mario Poirier came aboard in October and immediately went to work helping to build duck boxes on October 22nd. By my count, we now have 41 paid up members as of Oct 31st. There are about 14 old members who have yet to renew. You know who you are and we’d love to welcome you back for 2011.

That was the summer that was
This past summer was pretty challenging for the club. Once the snow melted, our first problem was dealing with the two mowers that had broken at the end of last summer. First up was the old red Lawn Flite. The estimate — more than $1000 — proved too steep, so it was pushed back into the shed. Repairs to the yellow Yard Man turned out to be more reasonable, so that one was fixed and put to work. Meanwhile, our 31-year-old Kubota came down with a bad case of smoke escaping from the engine. It only happened when the engine was running, so we put it away and the problem hasn’t reappeared. Still, some day we’ll have to start it up again. For a variety of reasons, this has not yet been addressed. The biggest reason was the fact that from the start of July we have rarely been able to get into the sanctuary as the range has been very busy. In the meantime, the rains in August and September meant that when we did get in, our two little mowers, and their drivers, were pushed to their limits.
It wasn’t a great summer for the ducks either. On June 10, our wildlife director, Austin Taverner, sent this summary of the box checks to that point: The numbers of eggs laid and hatched is down a little from this time last year. We have a few late nests started so hopefully the hatches will be good for them. The number of abandoned nests is similar to recent years and is always a mystery. We still have a small number of eggs being removed from some nests, but have yet to be able to get a picture of the culprit(s) with our trail camera [see below, ed.] – the disappearance of eggs is mostly happening to nests with more than one female laying, and we suspect the ducks themselves are removing eggs. Too many eggs in one nest can cause problems as Tom Irwin found out last week in one of his boxes that originally contained 19 merganser eggs: only four chicks hatched and got out of the box safely; five dead chicks, two eggs with chicks partially broken through and eight eggs with chicks inside but not breaking through were found in the box.
Things didn’t get better and at our October meeting Austin reported that the number of eggs laid in the 61 boxes we monitor through the summer was very low this year and the hatch was even lower. We counted 411 wood duck eggs laid and only 174 hatched (42%). Hooded mergansers had an even worse hatch rate, with 268 laid and 91 hatched (34%). On the other hand, the number of merganser eggs laid has gone up significantly in the last two summers. Most of the unhatched eggs were due to nests being abandoned, perhaps because the below average snowfall last winter and the dry spring had our ponds shrivelling up. Austin also reported that most of the abandoned nests had signs of a struggle, indicating that more than one female was using the nest. One positive was that there was very little normal predation — when all eggs are missing.
Summer Box checks
Every year we face the dilemma of what to do about cold eggs in the nest boxes. To get advice on this issue, Austin asked our Scientific Adviser, Rod Brook:
Hi Rod; Every year I struggle as to what to do when we have cold eggs, with little down, for several weeks after completion of the wood duck and hooded merganser clutches. We normally use three weekly visits to the box as a rule of thumb to determine if eggs are abandoned (if they are covered with a six to eight inch starling nest every week then there is little doubt). We then clear the box and make it available for a possible new nest. If in doubt I give it one more week. Is this too soon to discard the eggs? My experience tells me that if incubation has not started by then it never will be, but I hate throwing out good eggs. Any thoughts? Aus…
And here is Rod’s reply:
Hey Aus; The female will start incubation after the last egg is laid so if you have a full clutch and cold eggs there is little doubt. The only time I would be concerned would be if it’s cold outside when you do your check and there is a chance the hen was flushed off for a half hour or more before you get to the box. Down is hard to go by early in incubation as it can vary a lot. If in doubt, you could carry a sharpie and number the eggs. If they are all as you left them the week before (not turned and in the same order) then you can be pretty sure the nest is abandoned. Females turn and rotate the eggs to the centre constantly. Rod
With this advice, we have begun to carry markers when checking nest boxes, and numbering the eggs when we suspect a nest has been abandoned. It has generally worked well, but there was one time when Austin returned to a nest to find that four of the numbered eggs had been removed and replaced with four new eggs. In another box, he cracked open an egg he thought had been abandoned only to discover a chick ready to emerge. He carefully returned the egg to the box and the following week found that it had successfully left the nest.
Trail camera
Austin’s June 10th report refers to the mystery we have been trying to solve for years about “who is robbing the nests?” You’d think with all the retired cops in the club, it wouldn’t be hard to get to the bottom of this problem, but you’d be wrong. So last year we purchased a trail camera that takes pictures automatically and set it up by boxes that have been robbed frequently. Al Beaulieu has led this project, with help from Ben Mancini and Mary Lou Porter.
The results have been disappointing — the only predator caught in the act was a crow and it wasn’t able to get at the eggs. Most of the time there’s no indication what triggered the camera. Whether the problem is with the camera or us is yet to be determined. Perhaps the ducks fly into the boxes too fast for the shutter.

Purple Martins
Despite disappointments with the ducks, there was some good news this summer too. We were pleased to welcome back a noisy flock of purple martins after a few years of absence. Once they had left, Ben checked the martin apartments to find out what he could learn and to clean them out for next year. In one of them, he found evidence of 11 purple martin nests. One nest had two dead chicks and two unhatched eggs. Another nest also had two dead chicks. In the other apartment, Ben found four grackle nests, all on the lowest level of the complex.
And he had this to say about the martins’ nests: “I never realized how bad the smell was in those nests — much worse then Austin’s sardines!” That’s pretty bad.
Bird sightings
The best bird sighting this summer had to be the male black crowned night heron that perched near the sheds one evening in June while we had our dinner. The great egrets that arrived later in the summer were another highlight. We also had a pair of great horned owls that successfully fledged two owlets in the Heron Pond heronry. And let’s not overlook the fact that three osprey nests were active on the sanctuary this summer, one by Rifle Road, one at Innes Point and one by Tenth Line Road. This is not a record — once there were seven active nests on the sanctuary — which has Ben thinking we should build another platform and invite them to our part of the property.

Tony’s Hide
While going through some old minutes, Bill found this note from the 44th General Meeting of the ODC held on November 4, 1969: “A suggestion was made that a blind should be built in the fields at the compound for purposes of filming waterfowl.” Bill says he didn’t see any follow-up at the time, but last year Tony came up with the same idea, and acted on it. Last winter, he designed a pre-fab hide, which he then built at home. In the early spring he brought the pieces out to the sanctuary and with some help from his friends, put the puzzle together. The result is a spiffy new hide near the Dike pond. Bill expressed some concerns after a particularly windy day in June, since you never know if that pre-fab stuff is built to code, but the structure came through with flying colours.

Feeding deer in winter
Now that winter is almost upon us, it’s worth reading this article by Jim Gourlay, called “Killing with kindness.” Bill got it from Saltscapes, a magazine from Atlantic Canada.
Here are six reasons why feeding deer in the winter is a bad idea.
1. In northern climates, deer “yard up” in winter, sticking close to an area offering both food and shelter—where they beat down regular paths through the snow between the two areas. When “free” food is offered, the yarded herd will concentrate in a smaller area and become highly dependent on a single unnatural food source. In such a single food source situation, stronger animals will push the weak aside, and those animals will be denied food and starve. Wild deer that are dispersed in a natural wintering habitat rarely exhibit this behaviour, allowing the younger deer an opportunity to feed.
2. The dependence situation created can also cause deer to abandon their natural tendency to conserve energy in winter, with fatal consequences if the food source suddenly dries up (during that winter vacation, or if the person finds it too expensive to do it properly, at about $60 per deer per four-month season).
3. Deer, so concentrated, also become more vulnerable to the spread of disease, predation, harassment by domestic dogs, and highway collisions.
4. And, speaking of disease, the bovine tuberculosis and chronic wasting disease outbreaks that have decimated wild deer herds in western North America can be exacerbated by deer feeders—uneaten food in the corners of the feeders may facilitate harmful bacterial growth.
5. Deer, attracted by a regular free meal, will also help themselves to expensive shrubbery and fruit trees. Their concentrated numbers will hinder the natural regeneration of wild tree species in the vicinity.
6. And, too often we offer them the wrong food. In winter, apples just don’t cut it—they are like candy to kids. The smell will attract deer, for they clearly enjoy the taste, but the fruit provides virtually no vital nourishment to meet their metabolic needs.

THE PETRIE ISLAND WOODDUCK NESTING BOX STORY
by Grant Hopkins (with additional vague recollections from Bill Bower.)
In 1987, I was president of the Ottawa Duck Club and Bill Bower was vice-president and both of us lived in Orleans. We thought that a wood duck nesting box program along the lower Ottawa River from about Beacon Hill to Rockland would be a good conservation project that we could look after more conveniently than heading down the Queensway each week to the Shirley’s Bay sanctuary. The only wood ducks seen along the lower Ottawa at this time were only passing through.
I put together an application to the Ontario Ministry of Natural Resources (MNR) in March 1987 for funding under the Community Wildlife Improvement Program (CWIP) which was eventually approved and the club received the requested funds in 1988 (around $800 as I vaguely recall.)
The project involved installing wood duck boxes in five locations — the Duck Islands opposite the Ottawa sewage treatment plant at Green’s Creek; Green’s Creek itself; Petrie Island; the islands west of Rockland in Lafontaine Bay; and in Clarence Creek east of Rockland. The total number of boxes to be installed originally was 30 but we stopped at 21 located as follows:
- Lower Duck Island – 4
- Green’s Creek - 3
- Petrie Island – 7
- Ottawa River at Lafontaine Bay – 4
- Ottawa River at Clarence Creek – 3
(Today we have 13 boxes at Petrie Island, ed.)
Getting approval to locate these boxes was a bit of a pain as a number of agencies were involved. Approvals were eventually obtained from the Regional Municipality of Ottawa-Carleton, owners of Lower Duck, Petrie Island and Green’s Creek; the Township of Cumberland for the Rockland area; and Ontario Hydro. We had planned to place boxes on Upper Duck Island, owned by the City of Gloucester, but after much prodding they refused permission because our boxes would interfere with future marina development planned for the island. I have yet to figure out who dreamed up this excuse.
In my 1988 status report to the MNR in April of 1988, I expressed my displeasure as follows: “The full support and encouragement of the various levels of government who owned or controlled the various locations were obtained in a timely manner. The only exception was the City of Gloucester, which, after much delay, refused to allow boxes on Upper Duck Island. The city seemed in a state of confusion over our conservation project and flimsy excuses were offered for denying the club a go-ahead. The matter was not pursued.”
In the same letter I reported that about 150 man-hours of volunteer labour had been involved in installing these boxes to date and that one box on Petrie Island had been occupied and 11 eggs successfully hatched. We at least enjoyed some partial success.
In subsequent years, we pulled the boxes from Green’s Creek and Lower Duck Island because of a lack of nesting activity. We had a few boxes used initially by woodies in Lafontaine Bay and none in Clarence Creek. This latter situation was rather surprising as of all the Rockland locations, Clarence Creek seemed to have the best habitat and most potential. One box was stolen from the creek and we eventually abandoned or recovered the others.
The RMOC, City of Gloucester and Cumberland Township are now history. Despite some ups and downs, the project can be considered a success from the results of Petrie Island alone. When we started we had no idea if and where the ducks might find our boxes to their liking. The fact that over 1,000 woodies have been hatched at Petrie since 1987 has made it all worthwhile.
