LP + Haldimand

I had grand ideas of heading down to the north shore of Erie to see some sparrows, driving along the lake in Haldimand County, then heading to the Niagara River, however, things were not to be.

Getting up this am, I realized we had gotten 10-15cm of snow overnight and there was serious lake effect (Lake Huron) snow still coming down at 6:30am. Anyways, I made my way down to Simcoe and realized there was pretty strong lake effect occurring even in Haldimand, so I made a detour to Long Point and checked out a few spots before heading east.

First up, I picked up the long-staying Smith's Longspur - so long, in fact that it is no longer a flagged species in eBird for Norfolk...!


Continuing, I checked Front Road in Port Royal, as the bridge area would likely be sheltered from the strong NW winds. Managed a few WTSP, and my year Sandhill Cranes and Brown Creeper. After this I headed to Old Cut, to check the feeders, and managed to get Tufted Titmouse, Red-winged Blackbird, a few Cowbirds, and more WTSPs, but missed the good stuff (Northern Goshawk, Fox Sparrow, Yellow-rumped Warbler and Gray Catbird) seen later by Adam and Taylor -- oh well!

After this I started heading back east, as the lake effect snow was now dissipating on the radar. Best highlights were a single Double-crested Cormorant near Selkirk and a Pied-billed Grebe below the dam in Dunnville (a great winter spot). I also checked out the conifer plantations at Selkirk hoping for some owls...but no dice. It was interesting to see the left-over banding operations from John Miles. 

With the wind being pretty persistent, and few birds, I decided to head straight to Vineland, where I had to drop some things off at an acquaintance and headed home. I always like checking out Haldimand County, especially in winter -- John Miles was on to something with his banding at Selkirk. All in all, managed to up my year list to 76, but who's counting.

On a different, tomorrow I'm off to the Cornwall for work and am really hoping for some Gray Partridge. That got me onto thinking...has anyone checked out the Brantford airport in recent years for them? I checked eBird and they were last there in January 2013 (15!) ....I don't see why they wouldn't be around -- who's going to check???

Way back in '04...I've seen GRPA as recently as 2011, which was also the last time I checked for the species.

2016 Big Year at a glance

At this time of year, I always like to see where I'd be at if I were doing an Ontario Big Year. So far in 2016, I've seen 294 species. Several of these species

Highlights:
Grace's Warbler (!!)
Common Ringed-Plover (!)

Crested Caracara (!)

 Added with these, a few nice self-finds, like these:
Swainson's Hawk
Western Sandpiper
Carolina X Black-capped Chickadee hybrid (obviously not counted in the species list)
Henslow's Sparrow
Neotropic Cormorant
Eurasian Collared-Dove

When this is added in, there's a total 51 species + 6 possible species seen in Ontario that I would have been able to see:

Bohemian Waxwing
Brant
Hudsonian Godwit
Red Knot
Long-eared Owl
Purple Sandpiper
Red Crossbill
Hoary Redpoll
Buff-breasted Sandpiper
Barrow's Goldeneye
Ross's Goose

Lark Sparrow December - Toronto
Black-headed Gull December - Niagara




Unlikely, but Possible
Little Blue Heron July - Harrow/Holiday Beach
California Gull
Northern Fulmar
Western Kingbird July - Rainy River

More Zion...

Last week the weather looked pretty promising early in the week for some late fall hawk-watching. With this in mind I decided to use some of my banked hours and took Thursday and Friday off to head down to Zion Road -- one of my newest and favourite eBird hotspots to bird.

I unfortunately got a late start on Thursday morning, largely due to the World Series insane game, however, it was a pretty exciting game. I made quick stops at the Ridgetown and Blenheim lagoons, getting a pair of Snow Geese at Ridgetown and the long-staying pair of Cattle Egrets at Blenheim.


After leaving Blenheim and getting onto Hwy. 3, it was evident that a great hawk flight was moving forward, I managed to get a light Rough-legged and a Red-shouldered Hawk quickly before pulling into the hawk-watch location at the end of Zion Road.

From about 11:30 until 2:30 the flight was right over-top of me, at the lakeshore. Highlights included 5 Golden Eagles, 429 Red-tailed, 62 Red-shouldered, 3 Rough-legged Hawks, and 2 Northern Goshawks! Here's my eBird checklist for the day: http://ebird.org/ebird/canada/view/checklist/S32358103




Friday, the flight didn't really materialize as I had hoped for, but I was joined by Nathan Miller. Nonetheless, Nathan and I made the most of our situation and enjoyed the morning flight of passerines, getting some pretty good numbers of things like Cedar Waxwings (523) and American Goldfinches (582), as well as a single Golden Eagle and Rough-legged Hawk. Our real highlight, however, came shortly after 11am, when an adult Broad-winged Hawk(!) flew over, getting harassed by some A. Crows. http://ebird.org/ebird/view/checklist/S32372589


And if this is pretty exciting to you as it is for me, there's a vacant piece of property for sale for $24,900 a few hundred metres from where I've been setting up to watch....who knows, but that property would likely have a pretty sweet yard list if a birder built a house there...

The road to Zion (October 22nd)

Don't worry, I'm not trying to get all religious on you...but with the perfect set-up for Saturday, my Dad and I motored down to just east of Wheatley for a hawk-watch at the end of Zion Road.

This isn't technically the wind map for Saturday, but it's pretty close (Sunday night - 11 EST).
For those who don't know, this little spot, at the end of Zion Road, likely like every other dead-end road that hits Lake Erie should be an excellent spot to do diurnal watches.

We did our hawkwatch from the end of Zion Road where it bends 90 degrees to the west
The wind set-up was so good, that driving down we passed through lake-effect rain(!) from London to the West Lorne onroute along the 401. I was getting abit worried that the rain would 'block' the hawk movement, but these worries were shortly lived.

Getting down to the Wheatley area, we checked the canary pond, north of Comber, where we saw a few shorebirds and some early-ish Tundra Swans (http://ebird.org/ebird/canada/view/checklist/S32160827).

After the Canary ponds, we went to Hillman, where we saw 5 Long-billed Dowitchers among a few other things (http://ebird.org/ebird/canada/view/checklist/S32160882).

After this, we headed over to the end of Zion to start our hawkwatch, only to find the one and only Brandon Holden - quite the pleasant surprise, if I might say so. Apparently great minds think alike. By this time it was about 10am and birds were really moving. Being right by the lake we were getting not only good numbers and great looks with the strong NW winds of hawks/vultures, including a juv. Broad-winged Hawk, but there also a decent number of waterbirds moving, with Common Loons being quite common as well as appearances of 2 Surf Scoters and 3 Long-tailed Ducks, both species that are fairly good in this part of the province.

Around noon, we were noticing that the hawk-flight was moving inland, so we moved up to Hwy. 3 and weren't disappointed. Our highlights for the day came in a short, rapid-fire over 20 minutes, starting at 14:20, when a juv. dark morph Swainson's Hawk flew by, quite close!!! I must say, I was definitely not expecting a SWHA, which was likely why I confused it for a weird male intermediate RLHA at first.

A few minutes late a nice light morph Rough-legged Hawk flew over, following the same flight line as the SWHA. If things weren't good enough, Brandon picked out a rufous/dark morph adult Red-tailed Hawk at 14:38! Talk about a day! We didn't stay much longer, as my Dad had some prior commitments, but all in all, a nice day with good company.

The Coves -- a new 'thing' in Ontario birding?

The title might be a bit dramatic, but I've been nonetheless enthralled the last few days with the notion that we, Ontario birders, may have our very own Cape May morning flight going on...it's just that we don't have to travel all the way to New Jersey to see it...

Rewind a few weeks ago: Barb Charlton, aka Barbed-Wire, and Big Country (formerly known as Tim Lucas) and I went down to Hatteras, North Carolina for some pelagics (I will be doing a blogpost on this at some point!) in late August. During one of our countless, random conversations during our 30 hours of driving Tim mentioned that he thought the Coves might provide a location where morning flights of landbirds could be observed. This was a really interesting idea and left me thinking a fair bit over the next little while about the location and the phenomenon.

Editors Note: For those that don't know where the Coves are....the Coves are the extreme western edge of Big Creek Marsh and the base of the Long Point peninsula, slightly raised above the lakeshore (~40 feet up?), where the vegetation from Big Creek marsh narrows to <100m of vegetation along the lakeshore. This geographical feature acts as a natural funnel for birds moving westwards, along the lakeshore.

Pardon my 'Bradon-esk' map making (they're not as nice as what Brandon would do); yellow star is where the Coves are. Yellow arrows are where birds would move (west along the point, west along the shore, and south along the Big Creek corridor), with lesser movements overland through the various green patches (orange arrows).


Fast forward to last week: I was able to take last Friday (Sept. 9th) off and luckily also had some conducive weather for songbird migration too -- north winds and slightly cooler temps.

I got down to the Coves on the 9th and immediately had Warblers and other landbirds migrating overhead, moving west. I was excited! Tim was right! Over the course of the next few hours I had about 2,000 birds that would be counted if I was doing a 'standard' morning flight at Cape May -- which is pretty decent. Warblers accounted for about 500 individuals, with American Redstarts (38), Magnolia (29), Chestnut-sided (11), and Blackpoll (7) comprising the main numbers (that I was able to identify). Other species like Bobolink (64), Rose-breasted Grosbeak (54) and Red-eyed Vireos (38) were also around in good numbers.

To top things off, I also had a Eurasian Collared-Dove(!) flyby! Pretty sweet! See my eBird checklist, here to see everything I observed: http://ebird.org/ebird/view/checklist/S31493708

Sunday (Sept 11), I managed to make it back down and again there was a decent movement, however, not as good, though I somewhat expected this after taking a look at the wind map the night before, looking at the wind field. Again, decent numbers of warblers, with ~150 individuals noted: http://ebird.org/ebird/view/checklist/S31528555

It was interesting to compare the 2 days that I've been down there so far; it appears that any day with a north wind could be good for a morning flight. I think the rarity potential for this site is excellent (look at my Sept. 9th checklist), with species like Dickcissel, Western Kingbird, Scissor-tailed Flycatcher surely occurring on a 'regular' basis, while other species like American Robins, Cedar Waxwings, Bobolinks, American Goldfinches expected to show up in huge numbers.

Birding on First Nations Reserves

That's an odd title. But it's true...they're pretty good for birding; it's just no one goes to them!! This morning I made the exception and took a drive over to Six Nations, just north of Hagersville. I wasn't really sure what to expect (both in terms of birdlife and hospitality), but it was really good.

I got there shortly after 6am this morning, starting at Indian Line and Seneca Road, where I worked my way north, zig-zagging throughout the reserve, ending at Indian Line, one road north of Hagersville.

My birding tour on Six Nations. Note the 2 pin-marks...

The reserve was/is largely like other reserves that I've driven through, with lots of old-field/scrub habitats and good chunks of forest. I had lots of neat stuff throughout the reserve, best were 2 singing male Cerulean Warblers (see map), as well as 4 Yellow-throated Vireo's, 1 Northern Waterthrush, 8 Blue-winged Warblers, and a singing male Purple Finch. Here's my eBird checklist: http://ebird.org/ebird/view/checklist/S30190936

I was pretty blown away by the numbers of things like Eastern Towhee's (21), Field Sparrows (22), Blue-gray Gnatcatcher (12), Willow Flycatchers (7), and Eastern Phoebe (12, inc. recently fledged young). While, given all the habitat, I only had 1 Ovenbird. However, having said this, it was quite windy this morning.

All in all a great 2.5hrs! The area screams of great potential (PRAW, YBCH, ACFL, PROW, etc.); I will be surely going back as soon as I can get some time to head there!

A closer look at breeding White-eyed Vireos in Ontario

As a biological consultant I work and follow Species at Risk (SAR) in Ontario very closely, as they essentially dictate my workload with respect to development applications. I consider myself someone who feels strongly towards the protection of our biodiversity and I've often wondered how and why certain species are classified as at risk and others aren't.

In recent years there seems to be an overall shift in the type of species being classified as at risk. In the late 80's/90's species that were designated as at risk were generally species whose ranges barely extended into Ontario (e.g., Prothonotary Warbler, Barn Owl, King Rail, etc.). In contrast to this earlier 'phase' in species at risk protection, the last 10 years has seen many common species, albeit declining at alarming rates, classified as at risk (e.g., Barn Swallow, Eastern meadowlark, Bobolink, etc.).

I think this recent phase in SAR protection has allowed some great work to be done for protecting species like Eastern Meadowlark and Bobolink. A bi-product of these 'umbrella' species being protected is that many other species (and not just birds either) that are declining and found in the same habitats (as BOBO and EAME as an example) are also being protected (e.g., EAKI, VESP, SAVS, FISP, etc.). However, in 'analyzing' these 'phases' of SAR protection there are a few species that were 'missed' during the 1st phase in the late '80's/90's, with White-eyed Vireo being one of them (I think).


White-eyed Vireos are an increasingly rare breeding species, found exclusively in the extreme SW part of the province. For fun I asked a few people I hold in the high regard with respect to songbird populations in Ontario: 2 out of the 3 people said <12 pairs/year; the 3rd person didn't specify a breeding population.
There is a general lack of information on the species likely in part because the species isn't classified as at risk and therefore doesn't receive funding allotments that species like Loggerhead Shrikes or Acadian Flycatchers may.

During the 1st Ontario Breeding Bird Atlas (OBBA) it was postulated that because the species was (and is still, relatively) common during spring migration, due to birds overshooting from the main US range, that the species was going to expand into southern Ontario as a breeder and become more established. The population estimate in reading the 1st OBBA was roughly estimated to be ~50 pairs, with 2 squares having a population estimate of between 2 and 10 pairs. WEVIs were recorded in 19 atlas squares (2 confirmed, 8 probable, and 9 possible):



Compare that with the 2nd OBBA (2001-2005) where WEVIs were recorded in 15 atlas squares (4 confirmed, 4 probable, and 7 possible) and it is relatively clear that the expansion predicted during OBBA 1 has not materialized, in fact WEVI has become scarcer, both in terms of spring migrants (personal observation) and breeding birds.


It's hard to say exactly how much of a population reduction the change from the 2 atlases represents; the total decrease of atlas squares is 21%, though in reality this doesn't mean too much. Taking a further look, eBird provides a good tool to document the species, particularly in the past 10 years, when eBird usership has dramatically increased. It is, however, clear that there are very few records during the months of June and July (over the past 10 years), as shown below:

No records were noted from Pelee Island.

Currently White-eyed Vireos are classified by the MNRF as S2/Imperiled ("very few populations; 20 or fewer locations, making it vulnerable to extirpation").

Looking into this a little more by comparing the data presented above with data we know regarding a similar species in Ontario -- the Acadian Flycatcher, is designated as an 'critically endangered' species. Acadians are also listed as S2, with a national population of 30-50 pairs (likely closer to 35 pairs). Both WEVI and ACFL have very similar geographic ranges.

Both species according to the Breeding Bird Survey have exhibited relatively flat population trends since 1966; however, to be fair WEVI has undergone +0.4% vs. ACFL at -0.4%, per Sauer et al. 2013/BBS.

ACFL screenshot for June/July for the past 10 years.
While both species occupy largely the same geographic ranges, they occupy different habitats: ACFLs are in older growth forests, while WEVI are found in old field/thicket style habitats. The last 30 years has seen some dramatic changes in populations of both guilds that inhabit these habitats. Species like the Yellow-breasted Chat have nosedived in Ontario (and the northeast), while the forests that existed in the 1970s/80s have matured and some species have increased that prefer these habitats. Having said this, I would expect WEVI to occupy pretty similar habitats to Chats and would expect that WEVI has also experienced a fairly dramatic decline, though few would notice this decline.

Anyways this is becoming a long blog post; I'd be interested to know what others think about WEVIs in Ontario! Should it be listed as a SAR? Are there more birds than I think? Are they increasing? Declining? Is WEVI declining in Ontario similarly as YBCH?
