Doug:

These are "beyond textbook" quality shots.

I especially like it that they are depicted swimming, which is where  
they spend most of their time (hungry for sushi, I guess).

Thanks for taking all that round trip travel time by auto and kayak to  
capture these two great shots.

Best,

Bob

Aechmophorus is the genus name of two grebes (family Podicipedidae)  
found in western North America, the Western Grebe (Aechmophorus  
occidentalis) and the Clark's Grebe (Aechmophorus clarkii).  These  
were formerly considered conspecific but were split in the last few  
years.

Outward differences include the extent of black on the bird's head,  
and the bill coloration.  Western Grebe has more black, extending  
below the eye, and a greenish-yellow bill.  The black cap of the  
Clark's Grebe does not extend below the eye, and the bill is more  
orange-yellow:

Technical stuff:  I wanted land or vegetation behind the birds  
reflecting in the water to avoid a glaring bright reflection of the  
sky, so in order to get close enough to the birds with this background  
I needed to be in the water looking back toward shore.  The kayak  
seemed the most suitable tool, being small, easily maneuvered and  
close to the water's surface.

I also chose early morning for these photos so that the light would be  
at a low angle and the water's surface would have a minimum of  
ripples.  As it turned out the morning hours also had the best quality  
light because our brief respite from forest fire smoke ended in the  
morning hours, and because the lake is popular with many people with  
paddle craft.  I was in the water by 7:30 AM and headed for home by  
9:30 AM
