Migration ramps up, bringing some rarities

 It is a busy time of year. Lots of birding to do, lots of photographs to process, and lots of garden preparation to do, among other things. I've been able to squeeze a few trips out to natural areas amongst the other things, and although the bird migration has been a bit slower than birders would like (surprise, surprise), it has definitely been fun to get out. 

Visits to Rondeau are always worthwhile. Warblers have been scattered and not in any great numbers, but that is bound to change soon. Many that do show up are hard to photograph against a bland sky and through branches, so more have been seen than photographed. When they are low down, I have a chance, as this Nashville Warbler and Yellow Warbler illustrate.


Getting ready for take off!
There are lots of sparrows, such as this Field Sparrow, shown next, a local breeding species. I missed an extremely cooperative Henslow's Sparrow. White-throated Sparrows have been by far the most common sparrow, but often are furtively scavenging amongst the branches and leaves on the forest floor.
One or more Northern Mockingbirds seem to be taking up residence at the north end of the picnic area. Maybe it will be a breeding species this year, so that will be nice to add to the Ontario Breeding Bird Atlas currently underway.
Swainson's Thrush is the most abundant of the Catharus group of thrushes these days.....
...and a few Veerys are showing up.
I have seen more Red Foxes lately, or maybe it is the same one on more than one occasion. This one decided to take a rest in a shrubby thicket, which made focusing tricky.
Eastern Chipmunks are plentiful, and occasionally will cooperate for the camera. I try and oblige.

I've spent a bit of time along the wetlands of Lake St. Clair, including at St. Clair NWA as well as the nature trails north and south of Mitchell's Bay. It has been very worthwhile. At SCNWA there are still some Ring-necked Ducks hanging around.

Canada Geese are quite common, not surprisingly and sometimes give some quite nice photo ops.
There were several young families out swimming around, with adults keeping a close eye on the surroundings.
What is a wetland without Red-winged Blackbirds! There are dozens and dozens.....
....and also lots of Swamp Sparrows, but they are much harder to get in front of the camera.
Occasionally one will be sitting up and trilling away, advertising its territory.
Right beside the observation tower is a broken off cottonwood, with a few holes. The top gives a good perch.
One can hear the 'witchity witchity' of the Common Yellowthroat regularly, but getting a photo as they skulk through the cattails, is another challenge.
Persistence sometimes pays off a bit.

Yellow-rumped Warblers are not confined to woodland areas. It is not uncommon to see a few in the shrubbery at the edge of the wetlands....

...while the occasional Palm Warbler will be hopping along the trail.

 

 

Birder along the SCNWA trail

Farther north, along Angler Line and either of the Mitchell's Bay Nature Trails also gives some worthwhile viewing and photo opportunities. Bald Eagles are almost a guarantee, with typically anywhere from 3-5 seen from various vantage points...

...and sometimes flying relatively close by. There are at least 3 active eagle nests within a relatively short flight, so it is not surprising that with the gradual increase in the eagle population these last couple of decades, the species is commonly seen.
 
Great Egrets nest in a colony at Walpole Island, a short distance away at the north end of Lake St. Clair. They also likely nest on the cattail islands out from Mitchell's Bay, so they are frequently seen feeding nearby.....
...or in flight from one feeding location to another.

 Along the trail, you can see coyotes! But not to worry, they won't harm you. They are signs that the neighbouring farmer has put out to presumably give the local Canada Geese reason not to venture onto the field and start eating the newly planted crops. I'm not sure how effective the signs are, as I did see geese on the field, but not right close to the signs.

The slightly lower water level has allowed for some mud flats to be exposed. From a distance, I could hear this Greater Yellowlegs quite clearly, and loudly, but from a distance I had a harder time seeing it. The yellow legs helped!

This Killdeer was not difficult to see at all.
A bit of a surprise was to see amongst about 30 Mute Swans, this first year Trumpeter Swan. Trumpeters are still quite a novelty in Chatham-Kent, but as the population slowly expands across southern and central Ontario, it will become a bit more common here, I expect. This one stood out with its still grayish feathering on the body and neck. It was at least as large as the nearby Mute Swans. The wide black area in front of the eye stood out...
...as did the slightly pointed feathering at the top of the beak, unlike the rounded feathering of a smaller Tundra Swan.
While I was in the Mitchell's Bay area, I got a couple of texts, first from Steve C, and a bit later from Jim B, alerting me to the presence of a White-faced Ibis that was along the Erieau Rail Trail. Jeff T had discovered it earlier that morning, and the word was put out. Instead of stopping at home in Chatham, I went as quickly as I could to get to Erieau. There were about 15 others there, and a fair number had already come and gone after having seen this rarity. It wasn't all that close to the trail by the time I got there, so a reasonable telephoto lens, and lots of cropping and processing of the digital images was required. Some folks who got there earlier had closer looks. However I shot a bunch of images, many of which were not all that great, due to the general cloudiness and back lighting, but here are a few that I kept.

It looks quite similar to Glossy Ibis, but the key differences are: 

-a white band all around the eye; the Glossy does not have as extensive a white line;

-the eye is dark red, not almost black;

-the bill is gray as opposed to brown.

Under less than ideal viewing conditions, it can be a challenge to distinguish between the two species, but with 'scope views, and photos that can show the differences, it can be determined that this is indeed a White-faced Ibis, and as far as we know, only the second record for the Rondeau checklist area.




With migration underway, what will be next????

Prairie sloughs and swales

The prairies of the mid-western part of the continent are well known for their incredible productivity as well as critical migration habitat for numerous waterfowl and shorebirds. I'm referring to the potholes and swales, an iconic feature of the prairies.

If you look at various parts of southern Saskatchewan and Manitoba, and the adjacent states, it is amazing how many sections of the landscape look like the following Google Earth image. That is an incredible number of potholes in a relatively small area! They vary in size, of course, and some years are wetter than others, so water birds have to adapt to whatever is available to them. The home territory where they hatched one year might be as dry as a bone when they go back to it the next year, making life challenging.

Many potholes are well away from the roads, and you don't see them. But fortunately some have easy access, and in some cases, the road goes right along side, or even cuts right through them. Some have steep sides, surrounded by dense cattail vegetation. They were used primarily by ducks, it seemed. But where there were gently sloping sides and muddy edges as the water level dropped, it was great for shorebirds.

We came across a few that I just had to stop at. One of them had a good variety of shorebirds, including:
Marbled Godwit
Willet
I did see a small number of Black-necked Stilt, but did not get any photos. There were lots of smaller shorebirds such as Lesser Yellowlegs, Pectoral Sandpiper, Least Sandpiper, etc.

Other birds commonly found in prairie wetlands were also present, including
Franklin's Gull
Eared Grebe
It was neat to see all these Eared Grebes in prime breeding plumage.

One slough had a Horned Grebe nesting just a few metres away from the edge of the quiet gravel road. I got their photos from the van.

Some young had already hatched, but one egg remained in the nest.
 Do you see the youngster peeking out from the far side of the adult?
One slough complex that I was particularly intrigued by was this next one. There was lots of room to pull off and explore one of the sizable cells that made up this complex, and the road went along another part of it. The water was fairly shallow in most places.

As I explored parts of it, I quickly realized how little of the overall complex I could actually get to. This next image from Google Earth shows the complex. I only got to see about 10% of it, primarily the part along the road.
There were at least 1000 shorebirds that I saw, of various species, including more than 30 American Avocets.



 A single Cinnamon Teal was resting amongst the shorebirds.
 A flock of 22 Marbled Godwits was flying around.
 Red-necked Phalaropes were plentiful.
 There was the occasional dowitcher, presumably a Short-billed
 Here, a Short-billed Dowitcher is surrounded by almost 100 other shorebirds. There was a huge number of Wilson's Phalaropes making up most of the shorebird numbers.

Wilson's Phalarope
 Various ducks, and quite a few Eared Grebes were around.
Given that I likely only saw about 10% of the pothole/swale complex, it makes one wonder what there was over the entire complex. It seemed especially interesting to shorebirds, quite possibly because there was a small cattle operation adjacent to part of it, providing lots of extra nutrients.

At another slough complex in Manitoba, I saw a ton of Eared Grebes and Am Coots...
 ...but by far the highlight was seeing several White-faced Ibis! According to the established range for this species (Sibley's Field Guide; Cornell U site), it does get into the very southern part of Alberta and maybe just barely into the southwestern corner of Saskatchewan. But apparently over the last few years they have been expanding. According to a contact I have with the SK Breeding Bird Atlas, they got their first confirmed breeding record in 2018, the second year of their first provincial atlas.
 Unfortunately the birds I was able to photograph were all in flight, and all chose to give me mostly back lighting, so these photos are much more heavily processed than I would like.

I was surprised by how few Yellow-headed Blackbirds I saw in my travels. Surprisingly I have seen more in Chatham-Kent this year (9) than I did across all three prairie provinces (2).

Clearly the pothole and swale complex of the southern prairies are wonderful places to visit at certain times of the year if you like birds. It makes the sewage lagoons of southwestern Ontario, as productive as they seem to be on occasion, look pretty quiet by comparison. A return trip to spend a greater amount of time is warranted!

The next post in this short series will focus on a very special place of the southern prairie provinces.
