Willow Flycatcher???
.
Willow Flycatcher seems to be the best fit. However, those Empidonax flycatchers are a lot easier to identify by song than by sight. By the looks of it, he was singing too.

Black Souldered Kite

This Black Shouldered Kite was hunting from a perch beside a rural highway in central Victoria. I stopped the car and was able to slowly approach him to about 20m before he flew off to another perch nearby. The winter morning sun catching the bright orange eye of this beautiful bird. K3 with DA*300mm and Pentax 1.4x TC (handheld). Both shots at 1/2000, F8 and ISO400

Chance upon this Sunda pygmy woodpecker (Picoides moluccensis, the smallest woodpecker in Singapore, Size range: 11.5-12.5 cm ) on last Thursday. A species of bird in the Picidae family, commonly seen in Brunei, Indonesia, Malaysia, and Singapore. Mummy feeding the chick with about half an hour interval (slightly different observations from the Coppersmith Barbet, both the father and mother take turn during the feeding process).









Sharing the video clip:

Merlin disagrees
Cornell Lab or Ornithology's Merlin Photo ID (beta) or the Merlin Bird ID smart phone app? If the former, what do its pattern recognition algorithms suggest?

Assuming the pic was taken somewhere in BC of a breeding-plumage adult: the pale underparts, completely pale lower mandible, and short primary extension eliminate Western Wood-Pewee. The lack of prominent eye-ring, inconspicuous wing-bars, short primary extension and completely pale lower mandible eliminate Pacific-slope, Alder, Least, Hammond's, Dusky and Gray Flycatchers. This leaves the northwestern subspecies of Willow Flycatcher (Empidonax trailli brewsteri).

When I loaded the second photo in Merlin Photo ID, it came up with five possible identities: Mallard (female or eclipse male), Red Crossbill (female or juvenile), Veery, Northern Flicker (Red-shafted subspecies), and Double-crested Cormorant! Guffaw

The PhotoID (beta) suggested Least as it's number 1 suggestion.

The other Empidonax were not even in the top 10.

When its comes to bird ID I'm going to go with pete-tarmigan over the computer any day Ben, he's forgotten more than I'll ever know
While we are on the topic of bird ID what is this guy, I think Swainson's and Merlin (beta) had this as first pick but it also had house finch as a possibility

How many of the Empidonax species and how many examples of each does it have in its database? It is only able "to recognize 400 of North America’s most common bird species based on images" (see below).

Not much basis to work from.

Of the hundreds of Least Flycatchers I have seen singing that species' diagnostic song or had in the hand while banding, all (in breeding plumage) had a far more conspicuous eye ring and wing bars than the bird in the photos, not to mention shorter bill with dark tip to the lower mandible. Alder and Gray are the only species that come close to this bird. In my experience, Pacific-slope, Least, Hammond's and Dusky all come in third place as candidates for this bird.

From the Merlin website:

"About Merlin Bird Photo ID

Can a computer identify bird species in photos? Researchers at Cornell Tech and Caltech have partnered with the Cornell Lab of Ornithology to train Merlin Bird Photo ID to recognize 400 of North America’s most common bird species based on images.

Sometimes Merlin gets it right, just like magic. Other times, Merlin gets it wrong–sometimes way wrong. What’s going on behind the scenes–and how can you help us keep improving Merlin’s accuracy?

The challenge: Asking computers to identify bird species is a challenge not only because some species look so alike, but also because their shape varies from moment to moment. On top of that, photographs of birds often include complex backgrounds, and the birds may be far away or blurry.

The solution: Computer vision researchers create “convolutional network” systems that use patterns in data to train the computer and improve its performance. These systems require massive numbers of images as well as accurate image labels such the type of object, and where the object is in the image. Fortunately, bird watchers are renowned for taking lots of photos and for contributing millions of observations in citizen-science projects. Thousands of people have contributed photos and tagged them to teach Merlin to recognize birds."

The detail on the back and wings is beautiful -- the primaries, secondaries and tertials stick out almost like 3-D.

I agree on Swainson's, based on my experience with them while growing up and working on the Prairies (not to mention subsequent trips to this species' range). Juvenile to be exact, somewhere on the gradient from intermediate to dark morphs. The dark morph gets common west of the Sask-Alberta border.

That would be something to see!!

Thanks for the comment Pete he was sitting on a fence post drying out after a very rainy day, the overcast but reasonably bright day gave me really nice light for the photo.
