D5 & AF-S 500mm f/4G VR-II on tripod.
Thank you for looking.

Hilarious and stunning at the same time! Well captured, Aguinaldo. The bird (I cannot identify) literally looks like a stealth bomber. :D
-
Akira it is a Frigate Bird, well known as a superb flier that robs other birds of their food in the air.😉

Thank you Akira.
It is a danger situation everyone experiences all the time without knowing it. lol

Thanks Mike.
I witnessed many of these steals during the photo session.
Perhaps you could also explain the white color of that shit. What kind of food processing these birds do?
-
Aguinaldo, sadly I'm not an expert in the analysis of avian shit, but have noticed over a few years that most birdshit is a dirty white, a part of their digestive processes I assume.
That has exhausted my knowledge of birdshit.

Wow, awesome detail on the cloaca action!!
-
Man dles that look convenient!
I am envious of some qualities of other digestive systems of the animal kingdom. Aerial dumps, digesting bones, etc.
-
Obviously J-A is the go to man with queries about birdshit. ;)
-
Perfect...this is very acid!
-
Mike, thank you for the identification of the bird. And, yes, I also observe that the birdshit is often dirty white. :D
-
Akira, my pleasure. ;)
-
excellent shots of the frigate bird Aguinaldo. Nice detail and lighting. These are very fast birds (unless hovering on the wind) and hard to photograph well. Also, like most birds shot upwards towards a bright sky (especially dark coloured birds) it is difficult to get the right amount of light under the wings and body to really see the detail (despite a little + EV). You have done extremely well in all these issues.
As for the "attack" , Mongo is sure it wasn't personal. Maybe they just like to shoot at any extra fine equipment for extra points.... ;D
always enjoy your images and don't let them hit that equipment.
-
Thank you all for the comments.

The white is actually urine, highly condensed. Reptiles produce the same. Both produce uric acid rather than the urea that mammals produce, and in doing so are able to excrete it with very little water.

Thank you for explaining it.
This acid may not be good for metallic surfaces.
-
Very timely...
At least this should bring to an end the continuous debate "should I use a protective filter or not"...
And don't forget your safety glasses next time!
-
Bill, thanks for the explanation. That makes sense and is interesting!

Well, I guess that's why Nikon developed the fluorine coating. ;D

;)
So Nikon's breakthrough technology would result from a collaboration with pan manufacturers? This is not sexy at all...
This soil release benefit is well documented as the "lotus effect", quite amazing actually. The nice thing about PTFE is that it works on polar and non polar liquids. Neither oil nor water will spread in a new PTFE pan... Is someone willing to try on his Nikkor? I would of course but don't have any of those...
Years ago I worked on the opposit effect: how to favor glass wetting by lowering as much as possible the contact angle of water, and how to prevent dewetting by designing micro-patchy structures (an array of hydrophilic and hydrophobic midro domains). That was a fun project... The goal was to reduce the visual perception of dirt on glasses. The resulting benefit was to fight the irresistible impulse to clean windows when they look spotted. Well, irresistible to some.
-
Olivier, you don't need to put an expensive Nikkor in danger to test the effect of the fluorine coating. Apparently Marumi EXUS protection and PL filters have fluorine coating, too. ;)

They seem not to need a tail to be good fliers.
Their tail is made of only 2 feathers.
