The History of Tufted Duck in St.John's, Newfoundland

The history of Tufted Duck in Newfoundland is a very interesting one. It perfectly highlights how quickly things can change in just 20-30 years. Tufted Duck, by all accounts is rare bird in North America, it is listed a code 3 species for the ABA area, meaning it occurs annually, but in very small numbers. In most places in North America, a single Tufted Duck gets people quite excited. After all it is a primarily a European species, breeding throughout temperate Eurasia and has yet to be confirmed as breeding in North America (more on that later). It is a member of the genus Aythya, which also includes the Scaup, Redhead, Canvasback,Ring-necked Duck, Ferruginous Duck, Hardhead (yes that's a real species, look it up!) and the Pochards. As, well, it's flashy, Primarily black and white, but it's head has an iridescent quality and of course the breeding plumage males have that tuft!

So anyway, what's the big deal about Tufted Duck and what's so interesting about it's history in Newfoundland? In looking at eBird data for Tufted Duck the first report for the species in Newfoundland was in October, 1986. Now it's entirely possible that that there are earlier records (and there probably are), but they would have been singles here and there, they were a legitimate rarity.

Starting somewhere in the early 2000's Tufted Duck numbers in Newfoundland began to increase dramatically. The chart below, which displays the high count for Tufted Duck in St.John's between the years 2000-2018 shows the explosion in their numbers. Our Tufted Ducks usually begin to arrive in early October and numbers build over the fall, usually peaking in early winter. The numbers then remain stable until May when there is a drastic decrease.
We used to be happy if we had a handful of overwintering TUDU's. Then one year we had a dozen, then 20, then 50. The all time high was 84 this year. How much higher can it go?

The working assumption is our Tufted Ducks come from Iceland, where they breed, then migrate to Newfoundland to winter, then returning back to Iceland in Spring. That seems strange because why wouldn't they just stay and breed in Newfoundland? There is plenty of appropriate habitat and the very similar Ring-necked Duck does quite well here. However, the instinct to migrate is very strong and likely strong enough to cause they birds to make the long trip back to Iceland each Spring. Having said all of that, there is some suspicion that a few may be sticking around to breed, since we have been seeing the odd Tufted Duck X Ring-necked Duck and even some suspicious looking Tufted Duck X Scaup hybrids. It may be just a matter of time before we get our first breeding record of Tufted Duck in Newfoundland.

Note the grayish wash on the flank, which is typical of RNDU, versus the pure white flanks of TUDU. Also note the partial tuft, which of course is absent in RNGU
Spread wing of the TUDUx RNDU. Note that the pattern of white in the wing is about mid way between what would be expect for either TUDU or RNDU

I would normally spend some time discussing the identification of Tufted Ducks and how they are best separated from similar species, however, I will discuss all of that and more in this winters Duck Identification work shop. In that workshop, you will learn everything you wanted to know, and more, about Duck identification in Newfoundland.

Little Bird, Big Voice!

I remember the first time I heard a Ruby-crowned Kinglet singing. I thought what the heck is that! I search and searched looking for what could be singing so vociferously. Then when my binoculars fell on a Ruby-crowned Kinglet I could hardly believe it. How could such a loud, long song, come from such a small bird!

Sine that time Ruby-crowned Kinglets have been the bane of my birding efforts on more than one occasion. I remember doing bird surveys and straining to hear distant warblers, when all of a sudden a Ruby-crowned Kinglet starts wailing away from the tree tops. These birds have attitude to spare!

However, if they aren't singing Ruby-crowns (RCKI) can be somewhat difficult to see and they don't always show that nice Ruby crown.
Ruby-crowned Kinglet- The ruby crown is barely visible in this photo
and is often not visible in the field
What is always visible is a bold eye ring, a wing bar and those yellow/gold edges to the flight feathers. As well, RCKI's constantly seem agitated and flick their wings nervously as they move about. This is something most warbler species, do not do (Ruby-crowns aren't warblers of course, but are often with them in mixed flocks). As well, it's worth noting their call note at this time, since they only sing during the breeding season, the rest of the year their scratchy call note is all you'll hear.

Ruby-crowns are one of the first arriving songbirds in Newfoundland often arriving in late April or early May, when it is still quite cold. Interestingly, they leave quite early as well, since their numbers  thin out significantly into August and they can be hard to find in September.

While they are in Newfoundland they do some amazing things, including lay a truly massive clutch of eggs. Ruby-crowns can lay up to 12 eggs and while each egg weighs on 1/15 of an ounce, the combined weight of the clutch can weigh the same as an adult Ruby-crowned!While you would think that all that singing and egg laying would burn a tremendous amount of energy, these frenetic birds are incredibly energy efficient and metabolic studies of Ruby-crowns have found that they can burn up to as little as 10 calories a day!

I'll leave you with a couple more photos of these little gems. See what I did there...gems...the bird's name is Ruby-crowned Kinglet...Ok, enough of that! Stay tuned for upcoming posts that will include more species profiles, quiz birds, ID features and much much more!

A red mohawk any punk rocker would be jealous of!

Old Friends Reunite!

I was looking through some old photos and came across one that I hadn't seen in a long time of two Yellow-legged Gulls, photographed together at Quidi Viki Lake, in St.John's, Newfoundland in early October 2011. While Yellow-legged Gull is a major rarity in North America, it has become somewhat of a Newfoundland winter specialty over the last 15 years or so, with one or more birds usually present from September- March. On this particular day I located two Yellow-legged Gulls together among a mixed flock of Gulls loafing in a ball field near Quidi Vidi Lake. While I was super excited  to see them, you can imagine their surprise when they saw each other some 2500+ km's from their Azores home! My fiance added the caption at the time.I thought it was amusing and figured I'd share it :)
YLGU's, presumably of Azorean origin. The individual on the right is perhaps a little more typical of fall birds with a more extensive hood of streaks. They are completely white headed by Christmas.

Species Profile - Yellow-bellied Flycatcher


In keeping with the theme of highlighting Newfoundland's breeding Boreal species, today I've decided to take a closer look at Yellow-bellied Flycatcher.

Arriving in the last couple days of May or early June, this diminutive flycatchers song is part of the sound track of the Boreal Forest, along with Fox Sparrow, Blackpoll Warbler and Northern Waterthrush- just to name a few.

It's song is an almost comical 'chebek', or sometimes shortened to just 'bek'. It also uses a whistled 'chu-eee', which is oddly similar to the call note of Semipalmated Plover! Aside from those two common vocalizations it also has a lesser used third vocalization, which is a burry, 'churrr' (listen closely at 1:21)note. It often uses this call when moving from branch to branch or during inter-specific interactions.
Yellow-bellied Flycatcher

Yellow-bellied Flycatcher is by far the commonest flycatcher in Newfoundland and is often the only expected Empidonax flycatcher in the Eastern half of the province. In some central locations and South Western Newfoundland, the Empid situation gets a little more complicated, since Alder Flycatcher and Least Flycatcher are also possible (the latter being somewhat rare). However, with some experience, separating Yellow-bellied from these two species is relatively straight forward.

 Yellow-bellied is just that, yellow! In breeding plumage at least, it is significantly more yellow below than either Alder or Least, which can be quite pale. It's is also a more even green above, in relation to our other Empids- both Least and Alder can have some grayish areas on the upper parts, with least sometimes being quite grayish on the back of the head. It's most distinctive facial feature is it's bold yellow-buff eye ring, which is often peaked at the rear of the eye. Least Flycatchers eye ring can be similar, but never as yellow. Well, this wasn't meant to be an ID Empid ID piece, I'll save that for another post!
Yellow-bellied Flycatcher (note the yellow belly!)

This has been a very trying breeding season for Yellow-bellied's this year with June temperature being, well below normal, with some areas experiencing heavy frost and even significant snowfall and freezing night time temperatures. Since Yellow-bellied Flycatchers feed almost exclusively on flying insects, they have been seen by meany people desperately searching for food on lawns and in other areas one would not usually see them.
Note the thick buffy eye-ring, peaked at the rear

Note the strongly bi-colored bill that I forget to mention in the body of the post!


Now into the middle of June, the Yellow Bellied's have been back for only a couple of weeks and they are already about 25% of the way through their stay in Newfoundland. It's a race against time for late migrants like the Yellow bellies. They migrate all the way from Central America to the northern Boreal forests, for at the most, a little over two months, only to turn around and endure a massive journey back to their wintering grounds. Lets hope our weather improves soon so these birds can get down to doing what they came here to do.

I'm not entirely sure what to talk about next, maybe something historical.

Some Notes on the Identification of Juvenile Crossbills

I received a couple of photos from local birder Shawn Fitzpatrick today of a juvenile Crossbill. He never had exceptional looks at the bird but did manage to grab several photos. Quite often Crossbill identification is relatively straightforward. We have two species to consider, Red and White-winged. White winged Crossbill (owing to its name) has white bars on it's wings. In fact, it's often referred to as Two-barred Crossbill in Europe. As well, males of both species are shades of Red and females shades of yellow, they are different tones ,and as I said, identifying them generally isn't overly challenging.

However, in case I'm referring to, the bird was a juvenile, so entirely streaked brown and the photos were from essentially front on, so you really could not see if the bird had wing bars or not.So here is the bird in question.
Juvenile White-winged Crossbill (Photo Shawn Fitzpatrick)

Let me explain how I went about identifying this bird. The first thing I noticed about this bird was it's bill. One of the differences in White-winged and Red Crossbill is bill size (there are many types of Red Crossbills with varying bill sizes, but typically, Newfoundland Red Crossbills have larger bills than White-wined, it is both thicker and longer). This birds bill struck me as somewhat thin, not appearing overly robust or strong and seemed to narrow a lot towards the tip.

The next thing that struck me was the length of the tail. One thing I have always noticed is White-winged Crossbills are a relatively long tailed Finch. Look at the birds tail in the second photo, notice, it's length notice how quickly it tapers as it extends from the birds back, almost like you pinched it between your fingers. Not look at the actual tail feathers. Notice how far the tail feathers extend beyond the under tail coverts, this bird has a tail. When you see them at some distance, their tail length is almost reminiscent of Pine Grosbeak- though certainly not as long.At any rate it is significantly longer than Red Cross bill, which at times hardly seems to have much of a tail at all. When you see Red Crossbills in the tree tops, you often don't notice their tails that much, since they are quite short. Note this, when you are viewing Crossbills in the future.


Juvenile Red Crossbill, Newfoundland
Juvenile Red Crossbill- Note the difference in bill size with the above bird. Note especially how the upper mandible tends to be thicker towards the tip.

One other feature that kind of struck me about the bird above was the pattern of streaking. The streaks seemed fine, on a relatively pale base, especially around the side of the face (ear coverts). I'm pretty sure this is variable and will change quickly as birds mature, but the bird in the first two photos, has a facial pattern kind of reminded me of Pine Siskin. Now look at the bird in the photo just above. Note how the face is a little more solidly coloured.

One other feature that I noted in the second photo above was the amount of fine streaking on the birds shoulders (scapulars). Note the juvenile Red Crossbills above, how plain brown the shoulders are. I'm not entirely sure how reliable these feature are, there are perhaps at best an accessory. It's something I'll continue to look for when I see these species.

I'd like to thank Shawn for send me the photos and inspiring this post.











The Charismatic Boreal Chickadee (Poecile hudsonicus)

One thing I have gained from guiding over the years is much greater appreciation for our native Newfoundland species. That is one of the great things about guiding, you never really get complacent about your 'common' local species, because you are always aware of how special they are to your visitors.

One species, we as Newfoundlanders, tend to take for granted is Boreal Chickadee. While it is quite similar to the much more widespread Black-capped Chickadee, there is just something about it. Maybe it's their insistance to fend for themselves, and not rely on bird feeders; maybe it's their hoarse voice. For whatever reason, they are a species that has always captured my heart and it's easy to see why it's such a sought after species for visiting birders, from more southern locales.

I'll leave you with several photos. Stay tuned for upcoming blogs, where I will continue to showcase some of our native Boreal species and will include some interesting identification tidbits as well!

Thanks for reading!


While perhaps not the best photo, I like how this capture the spirit of the Boreal Chickadee, unfazed by winters icy grip!



One of my favourite photos of the species that I've captured. This pose really ups the 'cute' factor!

Another Day, Another Post


 I'm really going to making a conscious effort to post as much as possible going forward. I would ask if you are seeing this can you please take a moment to like and perhaps share my Facebook Page.
Over time, I will be posting lots interesting quality content, there as well. It would really help in growing the Birding Newfoundland brand.

For now I will leave you with some photos, everyone likes photos right?! I have lots of ideas for some quality education content and ID articles in the coming weeks and months, so be sure to stay tuned!
Some of my favourite Newfoundland warbler species. Always challenging to photograph, but so rewarding when you get those nice shots.

One of the new things I'm decided to offer are personal photo trips. I will not tell you how to operate your camera ( I can suggest) because that's not what I'm good at! I will however give you advice about bird behaviour, help you learn bird song and provide you with a great deal more advice that can help you improve your images. Please feel free to check out my website.
