Yeah I was going to post something similar.
Here is something for bird photography with quick google search.

Unfortunately, it's got a few too Rockwellisms in it, though overall it has some good points. I'll rebut a lot of the silliness:
1. Yes, getting close is critical, but so is having the right lens, 135mm is not long enough- the dove shot with a longer lens wouldn't need a 15' approach, and the result wouldn't have to be as cropped.
2. Waders and a blind can help, but not all the time. A long lens helps even when you have waders and a blind.
3. Backlit bird shots may sometimes work, but they're not going to get you shots that connect with the viewer unless you're using fill flash.
4. I can hardly imaging a "famous bird photographer" who wouldn't pay attention to what the birds were doing or the light- funnily enough, I doubt the girlfriend became a "more famous bird photographer." "Big scary glass?" if it was that scary, we'd all be creeping around with smaller lenses, though how we'd get shots of Eagles fishing and dog fighting, I don't know.
5. Talking about an 18-55mm consumer-grade lens and showing a shot from a 105mm professional lens is disingenuous at best. Even with tame birds how close you are is going to affect their behavior and your images. The telephoto perspective is going to produce a better image, the longer focal length will produce a tighter crop and the longer distance will affect the bird's behavior far less.
6. Ken may love the Nikon 80-400VR, but the Sigmas are sharper and longer for the price (I own an 80-400VR, it's ok, but generally lives its life lent-out.) If you shoot a lot of birds, you quickly realize that the 80-400 is less than ideal in terms of IQ.
7. Anyone who's compared the Canon 400mm f/5.6 to the 100-400IS will happily grab a tripod- there's an excellent Luminous Landscape comparison that's Googleable for anyone who thinks otherwise. If your primary goal is great bird shots, only an idiot or someone shooting from a Kayak would choose the 100-400 over the 400/5.6.
8. The degradation from a 2x TC makes a 300/2.8 less than ideal if you're actually "serious." If you're on a budget, the 200-400 is the Nikon answer unless you also need to shoot sports- but if your primary use is birding, the 300 with a 1.4x or the 200-400 are your best options.
9. This was written before Nikon added VR to the superteles, and not updated. Nikon's 500mm (as well as the 400 and 600mms) now has VR.
10. I've never seen a shot from a digiscope printed at 8x10 that I'd hang anywhere. They might be ok for birders who want to illustrate life lists, but for photographers they're not really an option.
11. I adjust focus manually probably about 30-40% of the time. Perching birds are often behind lots of cover where AF systems get confused by branches in the scene. A manual-focus lens isn't that big a deal, unless you're an imbecile who can't focus...
12. Ken's obviously never developed his own slide film. If you want vivid colors, simply shoot with a one stop push, which is extra time in the first developer and full time in the color developer, or visa-versa (Yay! I'm forgetting!) I shot Velvia at EI 80 and Provia 100F at EI 160 all the time, and with today's scanners, I don't think cropping a print is all that big a deal or that much of a difference (not that I'm advocating slide film over digital, but Ken clearly has little experience shooting slide film outside of "load it and send it to the lab when it's done.") Provia 100F removed the necessity of shooting Velvia to get grainless slides, and anyone still trying to shoot wildlife with Velvia in 2006 is mostly dumb.
13. If it took him 20 rolls of film to get one good, but not fantastic wide-angle shot, that speaks for itself in terms of his ability to parrot stuff about shooting birds (pun intended.) Especially shooting at Bosque!
