Snowy Owl, globally Vulnerable

The Snowy Owl has recently been listed as globally VULNERABLE. See: http://datazone.birdlife.org/species/factsheet/snowy-owl-bubo-scandiacus or http://www.iucnredlist.org/details/22689055/0. Population size and the extent of the declines are both poorly understood; however, despite the uncertainty, there is sufficient evidence for a listing of Vulnerable. We don’t really know why the numbers are declining but reduced food supply (perhaps due to climate change) and the high rate of collisions with vehicles and infrastructure have been suggested.

For the love of pipits!

After a splendid season of surveying Sprague’s Pipits in Manitoba’s grasslands, I am feeling rather pipit-inspired and have decided to share a series of photos of different species from around the globe. Pipits are not as boldly patterned as their relatives the wagtails but the pack in a lot of mystique and offer a wonderful birding challenged to find and identify.

Sprague’s Pipit (Anthus spragueii), Manitoba, Canada:

One of the highlights of so much surveying in cattle pastures this year was getting some exceptional opportunities to SEE Sprague’s Pipit. I emphasise the word “see” because 9 times out of 10 one hears Sprague’s Pipit but cannot spot the speck in the sky. These grassland birds make their haunting song carry further by singing high in the air over the grasslands. This year though, having spent so much time in grasslands such as cattle pastures for #MBSARPAL (http://www.mbbeef.ca/sarpal/) and on  community pastures, I saw no less than six of them on the ground (more than I have seen on the ground in 15 years of birding in Manitoba). Here is one that shows the bird well (including the white outer rectrices) stitched together with a habitat shot that shows a pipit walking through some beautiful mixed-grass prairie. . 

Buff-bellied Pipit, a.k.a American Pipit (Anthus rubescens), Manitoba, Canada and Wyoming, U.S.A.:

The other pipit we regularly see in North America is known in North America as “American Pipit” but this species also breeds in much of Siberia and northernmost China and winters in Asia as well so most of the world prefers to call the species Buff-bellied Pipit. Different populations breed in Arctic, Subarctic or alpine tundra and can look rather different (some more pink in breeding plumage and some more buff). The first collage shows a bird in the subarctic tundra of northern Manitoba, Canada and a close-up of a bird foraging in the inter-tidal zone of Hudson Bay. The second collage shows a bird in rocky alpine habitat in Wyoming and then a juvenile on a boulder slope.

Yellowish Pipit (Anthus lutescens), Salta Argentina:

The Yellowish Pipit is one of the more widespread and smaller of the South American pipits. This species is found in grasslands and other relatively open habitat types from the dry zone of southern South America to the tropical wet savannas, even as far north as Panama. 

Hellmayr’s Pipit (Anthus hellmayri), Tucumán, Argentina:

The subtly beautiful Hellmay’s Pipit is an enigmatic grassland pipit, found most commonly in the drier grasslands of the Puna (as high as 3700 m ASL) but also in pastures in some contexts. Some populations are resident and some are migratory and there is the possibility that some subspecies may in fact be cryptic species. This composite shows the bird up close on a rock and in the typical Puna habitat it calls home. It reminds me a lot of our Sprague’s Pipit but perhaps with a more speckled face.

Rosy Pipit (Anthus roseatus), Sichuan, China:

There are a few pipits that have soft pink or red in their plumage and the Rosy Pipit is one of my absolute favourites. This collage shows a bird in breeding plumage in the high mountains of Sichuan, China. This species is an altitudinal migrant, breeding in the alpine meadows and grassy slopes of the Himalayas and eastern Asia, even at the snow line, and wintering in the mid elevations plains.

Olive-backed Pipit (Anthus hodgsoni), South Korea and China:

The Olive-backed Pipit is one of the more common and widespread Asian pipits. This species breeds in a diverse mixture of habitat types especially where the taiga meets the tundra and where the montane forest meets the alpine zone, and, at least in the breeding season, seems to spend more time perched in shrubs and trees than many other pipits. You can even find them walking on the forest floor or fallen conifer needles at times. Like the Rosy Pipit, the alpine populations migrate down slope in winter and some go as far south as Borneo. This collage shows a few habitat types and plumages (a bird perched on a shrub in breeding plumage, a bird on a lawn in spring and a bird on the forest floor in autumn). 

Tawny Pipit (Anthus campestris), Rajasthan, India:

The Tawny Pipit is mostly a Western Palearctic breeding species that winters in sub-Saharan Africa (Sahel) and parts of the Middle East and the Indian Subcontinent. The large and fairly plain (i.e. unstreaked) pipit is easier to identify than many other pipits. It is found mostly in dry habitats as shown here in western India on the wintering grounds. Although it can be found in grassland you will also find this species in sand, gravel, semi-desert and shrubland.

Plain-backed Pipit (Anthus leucophrys), Cameroon:

The Plain-backed Pipit is one of the African resident pipit species (i.e. does not migrate) and a striking bird with its rich tawny underparts. This species is found in savanna and grassland with scattered shrubs and trees as shown here (photo from Cameroon).

Subtlety and beauty

On a recent visit to the high Andes of Ecuador, I was absolutely delighted to find a truly extraordinary shorebird of the high elevation bogs and alpine tundra, The Rufous-bellied Seedsnipe (Attagis gayi). The seedsnipe are a small family (Thinocoridae) of only four species of rather stocky shorebirds, found only in South America, whose diet is largely vegetarian (seeds and plant material) unlike the majority of shorebirds.

These birds are exquisitely plumaged such that their camouflage is exceptional but when seen well the feather detail is also truly breathtaking. I will try to let the photos speak for themselves. The first photo shows two Rufous-bellied Seedsnipe in their habitat. Can you spot them? If not, take a look at the second photo for help...

If you spotted those birds, congratulations! Now here are two photos with a telephoto lens to show off their exceptional beauty up close and personal. 

I hope you enjoy looking at these photos as much as I enjoyed finding these magnificent birds!

Mammals of the Summer of 2013

While out birding or atlassing in Manitoba, I am often treated to exciting sightings of mammals and other fauna. This is half the fun of being in the wilderness! This post shares just a few of those encounters from this past summer, part of what made the summer so special.

We start with the obligatory Black Bear. I photographed this individual near Nanuk Lodge on Hudson Bay coast east of York Factory as they walked nonchalantly towards me.

 

In the very same area as that Black Bear was this beautiful young black Timber Wolf. I encountered this animal three times while atlassing in that area. 

 

Here are two photos of a black Timber Wolf hunting Canada Goose goslings in the same area. I first spotted their ears sticking up in a slight ravine along the coast so I crept ahead and got into position and waited for the wolf to race out. I didn't manage to get photos of the kill; however, once the wolf had captured a gosling they walked right in front of my hiding spot on a beach ridge allowing me these photos.

Who's looking  at you? (this wolf sneaks around to get a look at me)

Moving a little further north, this Arctic Hare put on a fabulous show for the crew and I near the Churchill Northern Studies Centre (just outside of Churchill, Manitoba).

A little further north yet again, I photographed this Arctic Ground Squirrel just north of the Seal River, the southernmost limit of their distribution.

 

This young Polar Bear was over-enthusiastically trying to pounce on an Arctic Ground Squirrel without success.

 

Photographing Polar Bears is one of the great thrills of being in northern Manitoba. Here, a mother and cub stroll across the mudflat near the Seal River Heritage Lodge. 

This male wandered through the fireweed as I was surveying - I obviously had to keep a close eye on him as he strolled by!

A large male, previously hidden in tall grasses, stands up to investigate a noise... can you spell "adrenalin rush?"

... well?

Sorry, time's up!

Usually a good rule of thumb is... let sleeping bears lie!

Damn, you smell good! (female and male interacting)

On second thoughts....

That's a little tastes of some of the summer's magic moments!

On the Open Tundra

Moving away from the treeline into the open tundra brings with it a lot of excitement for those of us who live in the south and don’t get to see tundra birds in their breeding habitat very often. Of course, one has to come prepared for the bugs, which can be absolutely horrendous up here… you get a SMALL sense of this in the photo below where I forgot to fan the air before taking a habitat shot…

(and that’s just the ones around the camera – there were many, many more around me!)

After wading through the numerous floating sphagnum bogs of the central boreal forest for much of June, the tundra offered the relief of walking across more open country  and I was greatly looking forward to that. However, it was not all easy as, especially around Seal River, I encountered many large willow swales that had to be negotiated, including a lot of weaving and swimming through the dense branches. After getting cut up and my clothing ripped I eventually lost a few toques and a mosquito jacket thanks to those willows. So much for easy walking! The other promise of easy walking that the tundra offers is embodied in the word “permafrost” – even when traveling through the dens of the Hudson Bay lowlands, you never sink to the same extent that you do in the boreal biome because usually the ground is permanently frozen justa  few feet below the surface (although in reality the permafrost is not evenly distributed). As anyone who has read anything about global climate change will know, changes to the permafrost are occurring across the north and could have huge knock-on impacts for wildlife and humans alike. Around the Seal River, I found several places where the permafrost was exposed, such as seen in the photo below where a chunk of soil and debris had broken off.

 

One of the biggest pieces of news from the Manitoba Breeding Bird Atlas (www.birdatlas.mb.ca) summer season was confirming Long-tailed Jaeger as a breeding species in the province for the very first time. Ken De Smet and Joel Kayer found a nest at Nejanilini Lake and I found three pairs near Schmock Lake. These are both inland tundra sites as opposed to the much more visited coastal tundra sites and could explain why they have flown under the radar for so long. As Long-tailed Jaeger are said to be less kleptoparasitic (steal food from other birds such as gulls and terns by forcing them to regurgitate their catch) than the Parasitic Jaeger that breeds regularly in Manitoba’s coastal tundra, they may be more confined to inland tundra away from the larger and heavier Parasitic Jaegers and where they can capitalize on lemmings and such. Having said that, there was no real evidence of a lemming peak in northern Manitoba this year and other lemming opportunists like Snowy Owls and Rough-legged Hawk were not found to be breeding.  We just have to keep going north to determine how common these birds are and what their breeding distribution in Manitoba looks like but we now know that they do breed, at least occasionally, in several locations in our province. So here are a series of photos of some of the pairs that I found at Schmock Lake, perched and in flight and from various angles and showing them in their habitat sailing across the open tundra with true poetry in motion.

For the benefit of those Manitobans who don’t see this species very often, the Long-tailed Jaeger features to look for in the photos below include:

• VERY LONG tail (the most obvious feature but from some angles parasitic can surprise you with a longish tail and Long-tails can have missing or broken tail feathers)
• evenly brown underwing with lack of strong white crescent as shown in adults of other jaegers and juvenile Long-tails too
• fine black line along trailing edge of upper wing (and underwing) that contrasts with the pale brown wing and mantle (Parasitic also shows a dark trailing edge but with much less contrast to dark brown of wing and Pomarine is even darker still with even less contrast)
• buoyant flight style (not so visible in still photos)
• clean white breast lacking smudgy brownish breast sides or near complete smudgy breast band as in other jaegers
• grey flanks and lower belly bleeding upwards towards clean white breast but lacking a clear demarcation from the breast (Parasitic usually shown dark undertail coverts clearly demarcated from white belly)
• pale grey legs (not as dark as other jaegers)
• short, all dark bill (but with long nail) – the bill is shorter than Parasitic’s and lacking the pale coloration at base of bill typically shown by Parasitic or the bicoloured bill of Pomarine

got that…. So look for those features in the photos below (I’ll post some photos of Parasitic when i blog about the coastal tundra)

 

One of my favourite aspects on the tundra is all the breeding shorebirds to be found. This next series of photos shows some of these in their tundra habitat. It is hard to say why I love them so much but it probably has something to do with their magical display flights and songs; raucous behaviour when you pass through their territories, often perching in trees wherever these are available so their calls carry further; and their stunningly beautiful plumage, be it cryptic or colourful, that is always breathtaking. Enjoy this series of the shorebirds that breed in Manitoba’s tundra (in no particular order)…

We start with one of my absolute favourites, the American Golden-Plover, a magical combination of crypsis and contrast, of camouflage and colour.  Their distinctive whistled call wafting across the tundra is a little bit magical and a photo doesn’t do it justice but nonetheless here is a photo of a calling bird in their tundra habitat followed by a close up.

Likewise, the beautiful Stilt Sandpiper, with their unique banded plumage. Here again are two photos, the first showing a Stilt Sandpiper in their tundra breeding habitat and the second a closer photo showing the beautiful chestnut coloration of the bird’s breeding plumage…

And why not show the same for the cryptically plumages Whimbrel, another awesome tundra denizen…

There is a great deal of variation in the sandpiper family, from the large Whimbrel to the tiny Least Sandpiper, shown here. The first photo shoes a Least Sandpiper in breeding habitat on the tundra, the second photo shows a bird giving a distraction display to draw me away from their nest, and the third shows one squawking at me from a lone tundra tamarack in protest of my presence. Trees are such a valuable resource up here because itf you want to broadcast a territorial call far and wide they offer an energy efficient way of sending your message FAR (as I have blogged about previously) so it is not uncommon to see many shore birds species in trees on the breeding grounds where trees are available of course.

Other shorebirds that breed up here include the Dunlin, Short-billed Dowitcher and Red-necked Phalarope as shown in that order in the three photos below…

And lest I forget another little beauty – the Semipalmated Plover. This sequence below shows two different individuals in distraction display, feigning a broken wing to draw my attention away from their nest or babies; followed by some photos of the babies stumbling in the grass and trying to hide in the open before running back to hide under the breast feathers of mom or dad… very adorable but i had to leave quickly to avoid stressing the birds and never got the photos i really wanted to them sticking their heads out… 

One big part of this year’s success was the numerous nests I found in northern Manitoba. Here, in addition to the ones I showed in the last post, are a few examples. We start with the big one for me – the first time in my life I have found the nest of Red-throated Loon and the first confirmed breeding of this species for the Manitoba Breeding Bird Atlas (www.birdatlas.mb.ca). The first photo shows the nest (not much of a nest really, just an egg laid in a depression) and the then the owner (actually the photo is of a different individual but once again, I had to leave in a hurry and decided not to return to the nest site as I was doing survey work and did not have a hide / blind with me).

Here are some more example – see if you can identify the nest before you look at the subsequent photo of the nest maker!

Did you get that?? They were:

Willow Ptarmigan nest up close

Willow Ptarmigan nest in surrounding habitat (did you spot the eggs?)

Willow Ptarmigan

American Black Duck nest (I tried to trick you by not showing the bird)

Horned Lark nest

Horned Lark

Savannah Sparrow nest

Savannah Sparrow

The Savannah Sparrow nest is intriguing. I flushed a Savannah Sparrow off this nest and the eggs for the most part are consistent with Savannah Sparrow; however, I still am uncertain about the identity of the pale bluish egg that accompanies the brownish Savannah Sparrow eggs…. Anyone with any thoughts on this, please get in touch!

Off to the coast in the next post!
