Geese Galore and Tons of Tundras

I've been meandering about here and there mostly around Chatham-Kent over the last few days, on the lookout for signs of spring migrants or whatever. It is a little too early for reptiles and amphibians to be out, and certainly too early for those early butterflies. It is nice that we are gaining several minutes of daylight each and every day, and it is only another month until the spring solstice! And with the slightly warming temperatures and bright sunny days, it seems that some of the buds of trees such as Eastern Cottonwood are getting slightly fatter. Or maybe it is just wishful thinking.......

Waterfowl continue to be part of the story of this time of year. Numbers are building, especially of geese and swans, but the diversity of ducks is also on the rise. There are several thousand Tundra Swans and Canada Geese in the general vicinity of St. Clair NWA, using the NWA as an overnight roost but heading out into fields to forage at various times of the day.


Canada Geese are quite abundant, and if one examines a flock closely, you may still find a bird with a coloured neck collar. This next photo shows a very small part of a flock of well over 1200 birds in a corn stubble field just east of SCNWA. Right in the slightly lower centre of the photo is a goose with an orange neck collar.
 A highly cropped version of that photo reveals the alpha-numerics (you can probably get a better look by clicking on the photo). They are U5U7. I noted this bird in the same general area almost exactly a year ago. I sent this photo and the report to a former colleague within the Ontario Ministry of Natural Resources and Forestry who indicated that this bird had the collar put on as an after hatching year (AHY) female up on Akimiski Island in James Bay, back in 2012, so this bird is at least 8 years old.
Neck collars on geese are not as common as they used to be, as some of the research that used this type of banding process has wound down, and also because the banding process has changed. By using a neck collar, the only way researchers find out about a bird's location is if the bird is shot or observed somewhere and even then only if the hunter/observer takes the time to report it. Nowadays things like small geolocators are put onto birds. As I understand it, communications cell towers can detect the individually coded geolocator almost continually so that researchers can keep track of individual birds without anyone having to have visual contact.

This is the time of year when Greater White-fronted Geese are most likely to show up, and that has indeed been the case over the last few weeks. More than a few flocks of Canada Geese currently in southern Ontario will have a small number of GWFG amongst them. This next photo does not show them really well, but there are two GWFG in it. The geese were not providing me close views, and even with fairly high magnification, they are not showing well, especially since they are a bit smaller than Canada Geese. The most obvious GWFG is at the extreme left, with a second bird slightly to the right of the first bird. The second bird's head is tucked in so that only a small part of the white at the base of the bill is visible.
 A little more obvious are these four Snow Geese: two snows and two blues. Actually the one Snow Goose on the left is noticeably smaller than the one beside it, having a slightly smaller body and shorter legs. It raises the thought that it might be a Ross's Goose, but a close view of the bill shows a bit of a grin patch, characteristic of Snow Goose. Undoubtedly there has been some hybridization between the two species at some point in this individual's background.
On one occasion a couple of weeks ago I noticed about 30 Snow Geese flying over the NWA, and in a discussion with the marsh manager of the NWA, he noticed over 200 Snow Geese recently.

Ducks are becoming a little more abundant as well, although there aren't a lot of this next kind.

While I was out today, there were two adult Bald Eagles in a field near some Tundra Swans. One of the eagles decided to take flight almost as soon as I stopped the vehicle. Even though it flew in the direction of the swans, I did not detect any particular alarm within the swan flock. Bald Eagles aren't an aggressive hunter compared to their relatives, a Golden Eagle. Not that a Bald Eagle won't hunt live prey, but they are more likely to pick off injured birds such as ducks, or wait for a dead fish to float by or pick off a muskrat. Tackling a live and healthy swan is much less likely to happen.
 
There seems to be a lot more sparrow types around these days. Song Sparrows have been quite few and far between most of the winter, but in the last couple of weeks, one will see them regularly.

I stopped by Bannerstone Conservation Lands a couple of days ago. It is a small naturalized area, about 7 ha in size, a few kilometres north of Rondeau. It was planted into trees and wildlife shrubs, with some of the area left as meadow, back in the early 1990s, and the owners donated it to the Lower Thames Valley Conservation Authority. It is worth taking a periodic walk around, and on this day the most noteworthy bird species I came across was a Fox Sparrow, one of the few I have seen this winter.
The shrubby pasture along Stefina Line, just a bit southeast of Blenheim is a convenient stop along the way to Rondeau. Winter is the time to check for Wilson's Snipe or Northern Shrike. There are also Wild Turkeys, various raptors and other birds to be found, but never in any abundance. I seldom get more than 4 or 5 species during any one visit to the area. For example one day on the way out when I stopped, the only species I found was Turkey Vulture. There were two of them, and a raccoon carcass, presumably one that had succumbed to distemper in the previous few weeks, drew their interest. One bird was close by the carcass while the other bird was in a tree above. But they didn't appreciate me trying to get their picture. I left after getting a couple of shots, and they appeared to circle around and return to their breakfast.




 A little farther down the road is the spot to check for the ongoing, wintering Wilson's Snipe. It is a hit and miss proposition, with more misses than hits for most birders. On this occasion it was a miss. This raccoon was in the spot where the snipe is often seen, so after getting a couple of shots of the 'coon, I continued on.
On my way home a few hours later, I decided to check for the snipe again. And this time the raccoon had seemingly morphed into a muskrat! Not really, but the 'rat was almost exactly where the 'coon had been earlier.

I scanned up and down the creek, hoping that the snipe would materialize somewhere. I was about ready to leave when I noticed a suspicious looking clump about 75 metres or so away, partially hidden by some grasses. I moved to a better angle and checked it with the 'scope and bingo! There was the snipe sitting up along the grassy edge. This first photo shows the snipe at about 10X. Do you see it?
I managed to get a bit closer and using a teleconverter making it to 14X and then cropping the photo, this is what I ended up with. As far as I could tell, it didn't so much as move a muscle or feather or blink.


Waterfowl should be quite abundant over the next few weeks, and in Chatham-Kent places like St. Clair NWA, Erieau, Shrewsbury and Rondeau will be excellent places to observe them.

The Wings of Spring festival at Rondeau is scheduled for March 9-17, 2019. For more information about this festival, check it out here.
