Re-naming our birds: Upland Game Birds, Loons, Greebes, Tubenoses & Pelicans



The POS list returns!! (see previous post & explanation here)...





Gray Partridge = Hungarian Partridge (back to the old / no hiding your ancestry!)

Ring-necked pheasant = Asian Pheasant (ditto)

Wild Turkey = Feral Turkey

Common Loon = Great Northern Loon (stealing from Europe here)

Pied-billed Grebe = Ring-billed Grebe

Horned Grebe = Flared Grebe

Eared Grebe = Tufted Grebe

Audubon's Shearwater = Complex Shearwater

Wilson's Storm-Petrel = Patter Storm-Petrel

Leach's Storm-Petrel = Northern Storm-Petrel

American White Pelican = Snowy Pelican






I thought about re-naming the Red-necked Grebe the Trump Grebe, but I didn't go there... I didn't !!! I didn't do it.

More to come...

A little more rarity weather



Can hardly complain with the weather this fall... Great conditions & great birds... Another interesting low pressure system is poised to pass near/through the Great Lakes early this week... Once again the winds may be lining up a little better for Wisconsin/Michigan & area than Ontario/New York - but everyone should get in on the fun...

I'd say this is more of a "classic" fall low - with lost of moisture - although not exactly "classic" with only moderate winds... Here's a rapid breakdown:


Early Monday: Monster 979mb low to the west... Precip-free southerly winds moving into Michigan & Ontario... This is near "peak" for this event, but as of writing (Sunday) they've already started...




Early Tuesday: low stays at max intensity for ~24 hours then starts to weaken/become "cutoff" - however a lot of energy has been pulled into the S. Great Lakes by this point - including moisture...




Early Wednesday: Primary low is weakening fast, new low pressure forming near James Bay and also near the east coast... Odd/fun wind structure pulling into the southern Great Lakes where post-frontal (cutoff low) SW winds (and potentially some warmth) are reaching the region, despite the fact this would normally be the "cold" side of the storm



Early Thursday: The east coast low has left, and the "primary/weakening" low phases with the "James Bay" low, giving us another shot of fun wind/weather (and by this point, genuinely colder air)... The wind doesn't "come from" anywhere all that interesting, but should help get whatever birds are around/left (gulls, ducks?) moving. 


Early Friday - the "phased low" hangs around and weakens, but may be in a good position to bring even more N winds off of James Bay (which eastern ON birders thoroughly enjoyed this week)... Nothing too special, but a fun setup for the fall - anytime. 



Keep your eyes peeled, and find some late-season birds to enjoy!

Re-naming our birds: Waterfowl



Some of our bird names suck. So I've taken the liberty of creating my own Personal Ornithological Society and will begin the long-overdue task of renaming these birds. To begin: Waterfowl...



Greater White-fronted Goose = Prairie Goose

Ross's Goose = Snowflake Goose

Brant = Sea Goose

Cackling Goose = Viceroy Goose

Mute Swan = Grunt Swan

Gadwall = Plain Duck

American Black Duck = Eastern Black Duck

Mallard = Common Duck

Blue-winged Teal = Pleasant Teal

Green-winged Teal = Tiny Teal

Common Eider = Great Eider

Surf Scoter = Showy Scoter

Long-tailed Duck = Arctic Duck

Common Merganser = Great Merganser




I highly encourage all birders to create their own POS List! Then let me know (or comment) what changes you'll be making to Waterfowl...

More to come...

Rapid-fire weekend weather breakdown...






Thursday: Precip-free strong SW winds from a distance (decent contrast between high and low centres as the cause)



Friday: Strong low, turning a bit cyclonic here... Strong S/SW winds and warm air in the S. Great Lakes..



Sat: Low over the Great Lakes.. "Cold side" pushing through S. Great Lakes mid-day... 




Sun: some odd phasing of low's between James Bay and the east coast results in a "long distance" northerly wind event, cold temps and lake-effect snow bands...



Mon: Winds waining, still northerly and cold



Could be fun! Depending on what you want to look for... Or how tolerant of the cold you are??

Hypothetical "catch basins" for Great Lakes birding hotspots



Yes, this post was written with the recent Sagebrush Sparrow at Whitefish Point in mind...

Three hypothetical "Catch basins" for Great Lakes birding hotspots...

Legend:

Red = overland migration / concentration (primarily diurnal migration, such as hawks)

Black = overwater migration / concentration (primarily waterbirds like ducks, jaegers, etc)

Purple = overwater concentration (primarily songbirds, shorebirds, etc) - eg,/ birds that find themselves over water but are looking for land...

... I've also tried my best to keep the scale the same - so each figure & basin you're viewing should be comparable to other sites...



Whitefish Point

RED: 

Massive "Catch area" for birds moving in from the southwest. This is where records like Short-tailed Hawk come from... It is also potentially the cause of many mega-rare species that arrive on SOUTHWEST winds (Eg,/ Lucy's Warbler, Hepatic Tanager).... I somewhat suspect that this recent Sagebrush Sparrow didn't "arrive" in the Great Lakes yesterday --- it just finally wandered its way to Whitefish yesterday (this would be a similar process to the Grace's Warbler at Pelee this spring

BLACK:

Whitefish has a massive "catch area" for waterbird movement/migration (hence their awesome counts) - but also vagrants.. This is why they have so many Ancient Murrelet records... 

PURPLE:

For birds passing over water and looking for a place to land (eg,/ Nocturnal migrants) I would guess that there is not an exceptional catch basin... YES - it would be very good given the location of the point related to good migratory weather (eg,/ SW or NW winds) but as we compare with other hotspots, I'd say it's the smallest factor of the three in bringing volume or rarities to Whitefish.






Long Point

RED

The catch basin for diurnal migration isn't massive (imo) for the point... It is possible under specific weather conditions for this to be greatly expanded, but with typical winds/weather I would suggest that the point itself does not benefit from its geography in this way... (eg,/ a wicked west wind would be ideal, SW or N would be average)... 

BLACK

Lake Erie is a great place for waterbirds (volume and rares) but the Long Point catch basin is simply the nearby waters... Specific weather will really help, but the norm is only a degree better than lakewatching would be at any other vantage point on Lake Erie or the Great Lakes in general... 

PURPLE

Boom. Long Point has an exceptional "over water" catch basin - particularly in spring or SW winds in general... Something that hurts its status is the fact that multiple places can receive birds under these conditions, rather than one specific site (eg,/ you can't be at the tip and breakwater at the same time) but it sure helps ratchet up the list... I would bet some benjamins that records at the tip of Long Point such as American Oystercatcher, Varied Bunting and Hooded Oriole were brought in under this effect (over water, looking for a place to land). 




Point Pelee
RED

Pelee is Whitefish Point in reverse (or is Whitefish Pelee in reverse?) in terms of volume-migration and rarities... Pelee catches birds going south... This means awesome hawk migrations in the fall, and re-orienting vagrants in the spring (Grace's Warbler, Carolina Chickadee, Black Swift) The basin could potentially be extended into Michigan to the NW, but it's really quite hard for me (or anyone!) to say if that effect truly takes place... 

BLACK

Similar to Long Point, Pelee likely sees waterbirds from a relatively small area... It just happens to be a bird-magnet type region like the western Lake Erie basin... So you get awesome volume of Bonaparte's Gulls and the occasional/associated Ross's Gull... A notch or two above the Great Lakes norm - but not "out of this world" results... 

PURPLE

I suspect Pelee is hampered by Pelee Island in terms of "catch basin" of birds coming from off the water... They have other options in many directions, so the basin is quite small.. I suspect this is part of the reason why there is no particular concentration of vagrants or migrants from over-water on a regular basis (similar to Long Point and hawk flights, suitable weather is the exception and not the norm)... Yes there was an epic drop of migrants at Pelee this year on May 11th - but there was equally insane numbers at Pelee Island... IF Pelee Island were wiped of the map - would there have been 3x more birds at Pelee??




This is a rapid-fire un-edited post, and part of a bigger idea in terms of what truly makes a birding hotspot enjoyable (and when)... I wanted to get it out of my head - which is how these things end up on the blog... Perhaps more later (or perhaps not)...

Two quick case studies on the same topic before I go:



Caribou Island

RED

Hypothetically there is no effect of this whatsoever. 

BLACK

Hypothetically an average location for waterbird concentrations.

PURPLE

Hypothetically an AMAZING / very large catch basin of things lost over water... Presumably this is what pulled some of the rarities observed here to the island (Clark's Nutcracker, Black-headed Grosbeak, spring Purple Sandpiper)... In theory, spring and fall should be good here (with spring perhaps better)  --- and --- in theory --- the right weather conditions could lead to some truly spectacular fallouts from time to time... 




Netitishi Point

RED/PURPLE combined

Presumably the point-effect is decent, but nothing particularly special when compared to these other sites...

BLACK

The catch basin for waterbirds is off-the-hook... Just a question of A.) being there and B.) actually having them visible due to distance or conditions... 





OK! That's it...

A little more rarity weather a'brewin'?





Nothing SPEC-tacular, but at least two more low pressure systems packin SW winds and a general lack of precipitous on route.


Saturday morning:


850mb winds, pushing from Texas to ON


Tuesday morning:


A lack of rain in the southern Great Lakes... 


Yet some ballin' SW winds (and a high-vorticity-ish dryline of sorts?) 



Neither event should be particularly long-lived, which may not be 100% ideal - but the formula is there... 

Question is - what will show up? Is it getting a bit late? It's not quite Cave Swallow weather, but maybe it's close enough??? Maybe we'll get more Cattle Egrets??? Will Cattle Egrets continue to move north, so long as the temps are >15C??? What if we get another western-goose-invasion??? Will it be Ross's Geese this time??? Snow Geese??? Where does one go to "find" rare passerines in this weather??? 

Stay tuned...

White-breasted Nuthatch movement





Have been seeing White-breasted Nuthatches EVERYWHERE recently...

Not expected... (including places like Point Pelee - where I saw 5 at the tip TOGETHER recently)

Didn't bother to do  a quick search of eBird, but I assume one would  fimd several other "new" or "high count" style records - wherever they aren't expected - in the last month or so....

(insert your ebird checklists you found here)


---


So - keep your eyes peeled for WBNU!! Perhaps this is a good time to look for other unlikely-irruptive species too? (Who knows?)

Rare bird weather is slowing down a bit (see the previous post before the titmouse post) --- sooner or later a dynamite bird is going to be found somewhere OTHER than Chippewa County in the UP of Michigan...

Will it be you?
