Somedays, you go out for images of Beavers and Otters and all you get is the images you take waiting for them to turn up....
You'd swear it was duck dam, not a beaver dam.
There are always squirrels.
And my constant nuthatches and chickadees. I got these images with the K-3 and 55-300, trying to show a couple at the Cameron Road parking lot how much better you can do with portable lightweight lens then the 500-600mm glass they were using , in terms of getting the background etc., however, they remained fixed to their tripods in the middle fo the parking lot. It's fine buying expensive long glass, being committed to it's use when inappropriate, not so much. My images were taken buy ducking and dodging to avoid tree branches in the way. They kept complaining about the branches.
K-1 with Tamron 300 2.8 and Tamron 2x TC. Using that combo, I try and always use the 2 second timer (meaning I have to anticipate where the ducks will be in 2 seconds.). The camera reads 300mm instead of 600mm, and ƒ4 instead of ƒ8 and you can't depend on the SR. Considering it's a 2x TC the images are pretty good with the K-1. But that's it's limit, with the K-3's smaller pixels, I suspect resolution starts to suffer. But that being said, I bought it for use on the K-1 so I'm not at all disappointed.
And a pair of hooded mergansers out in Costello Creek. There is a place for long lenses, just perhaps not with birds as friendly as Nuthatches and Chickadees.
