February 1st – Introducing the Canadian Snow Bunting Network

A beautiful early morning filled with great expectations.

Traps set, snow on the ground.....where are the birds?

The beginning of the day.

 

Monday, the 30th, I went out with great expectations – 5 cm of snow covered the ground. It turned out to be just another of the disappointments this Winter has brought. I didn’t even see a Snow Bunting let alone band one.
So, I decided to turn to other parts of the country through the ….Canadian Snow Bunting Network, a group of banders and volunteers, now spread across the country, that formed a loose “team” to study the Winter behaviour and ecology of Snow Buntings. “The Network” started two years ago with a small banding group in Southern Ontario. The results have been so encouraging that we decided to spread it out to the rest of the country. Hence, the CSBN.
This blog will, on occasion, serve as a way for the CSBN and its members to inform the readership (and each other) about what they’re doing, and what they’re discovering – and just how interesting and  exciting it can be.
And since I don’t have any Snow Buntings here in Haldimand County, I think I’ll start with a couple of reports from the Montreal area – where they do have some snow…..
From Simon Duvall in Montreal:

Here are some news from the Montreal SNBU team. We just finished work at our Mirabel site where we banded 321 SNBU and 4 LALO in 8 trapping days. The last 2 days were pretty slow with only 12 birds in 2 days. It peaked on Jan 19, when we banded 94 birds. Here is the age/sex breakdown:

187 ASY-M

118 SY-M

7 ASY-F

9 SY-F

[Editor’s note: 95% of the banded birds are males.]

We have two other sites that are ready for us, one near Sherbrooke and one just north of Montreal.

Hope you’re having as much fun as we are.

Bonjour de Barnston-Ouest,

Same story in southern Quebec, where winter is a sad, wet shadow of its usual self. As soon as we have more than 5 cm of snow the bunting show up in force…had 175 a couple of weekends ago. Subsequently, we lost most of the little snow we had and numbers dropped off dramatically, increasing again yesterday with a few more centimetres of snow. This morning it was pouring rain…time will tell if it will be worthwhile for the banders to show up this weekend. For those interested in the site, I include a web-cam address. On good days the driveway and the barn roof are covered with snow buntings.

Cheers and happy bunting hunting.

The season started very slow in our back field, in Lanark, Ontario, with 4 or 5 Snow Buntings coming to feed. The numbers increased gradually and we’re up to about 60-70 birds now. Nowhere close to the numbers we had in the last couple of years, which was around 150.

Sage Advice from David Lamble, the pre-eminent bunting bander in the country, for those starting out and getting “antsy” because those d&$#%d birds just won’t go in the traps:

Hello All:

My ground traps are still effective — but there are some conditions.

First: I am off any major roadway — so the traffic is minimal.

Second: We have cloudy days, which are quite necessary for trapping the birds — the bright sunny days give me about 10% of the trapping of cloudy days.

Third: My area is very open with a fair bit of wind ( we are supposedly the windiest place in Ontario) — so the windy conditions seem to make the birds hungrier.

Fourth: I make a strong effort to capture the Shrikes and Hawks that follow the birds and move them several miles away (after banding, of course). So far I have captured 3 Shrikes and no hawks in January and not had any repeats — the more heavily hunted the Snow Buntings, the more nervous they are — just as the increased traffic at other sites seems to make them less likely to come to the bait.

So even on poor days, I will get 10 to 15 birds in my 3 traps every 30 to 40 minutes. Good days give me 25 to 50 birds every hour. When the weather was terrible, last winter, I might get 100 birds per hour.

Potter traps were used exclusively in Greenland, when the government was making an attempt to band as many Snow Buntings as possible. The array of Potter traps consisted of 20 or so on a long table. I had the impression that the trappers/banders had several tables, but I am not certain. Even so, the number of Snow Buntings trapped was quite small compared to the numbers our group captures each winter.

I have tried several Potter traps with limited success. I have never tried mist nets (beacuse it is too windy here, most days), but have heard of others using mist nets and a lure tape with some success.

Take care……………. David

Thanks to all that have sent in information and pictures.

One thought on “February 1st – Introducing the Canadian Snow Bunting Network

  1. IT was most interesting to see some of the comments here and i was wondering if someone could outline what they think are key things we can do to increase our success. For example i notice from some of the photo’s that people have traps set apart from one another is there an optimum configuration of how to put traps and corn piles?? As well i am finding that after on windy days the snow quickly covers the corn. I notice rick is talking about sunrise shots. Is early mmorning banding the best time to capture birds or is he just a passerine bander that has to get up early. Any suggestions would be wonderful as i am a totla rookie who just happen to live in a snow bunting paradise as we are pretty much guaranteed a good snow load every year so I should really learn how to catch these birds. Last year after being insopired by Rick we came home built traps and managed to only catch 60 so we have high hopes of ctaching in the 100’s but so far in 3 hours of banding have managed only 16 birds… rookies!!!! Any help will be appreciated. All the best from snowy northern ontario
