Hi,



In my experience, falls and minor accidents aren't really a problem for a scope in a soft bag if you pack some extra soft stuff, like some extra clothing, into the bag. The most common...

Hi Joachim,



The Kowa TSN-883 in its stay-on case fits easily in my Ortlieb Back Rollers, with room to spare.

Hi Renee,



Fascinating observation, thanks a lot for sharing! :-)

It's my impression that corvids are known to be playful, but I've never seen them do something just like that.

Hi John,



I'd think you'd need a mechanism to either fold the shoulder stock against the monopod, or to disconnect the two. You could then use the shoulder stock without needing to set up the...

Hi Bob,



Hm, now I wonder if it would be possible to combine a monopod with a shoulder stock to improve stability.

The advantage of a regular tripod is that it creates several large triangles. A...

I guess all the papers one might need for understanding that birds need to flap quicker if they want to go faster are probably already out there ;-)

Your fallacy is trying to argue that flap rates derived for characteristic speeds of species apply to an arbitrary section of flight of one observed individual.

Hi Mike,



You're using the concept of standard deviation outside the context where it's applicable, and that's an elementary fallacy.

You can only draw probabilistic conclusions from the standard deviations, so even in the best of cases, you could not rule out the Pileated Woodpecker with certainty.

It's just as elementary that the standard deviation is just an indication that the deviation from the mean is unlikely to be the results of mere random fluctuations.

Hi Mike,



How do you arrive at the conclusion that the filmed bird was in cruising flight?



It's 1 location, 11 flights, in table 7, which deals with flight speed.

Hi,



Yes. The reason is that you have 3 feet in a yard.

128 m/1000 m is the same as 128 yards/1000 yards, and it would be sane to leave out the unit altogether, because it doesn't matter.
