Description
Small Birds in FlightThis Journal is mainly a technical post about the difficulties of photographing small birds in flight. So, unless you are well into cameras, shutter speeds, response times and the like, probably checking out the photographs will be quite enough! But then, perhaps someone with more expertise than me (and that will not be hard) can help out with suggestions of how to overcome the difficulties. As bird photographers know, capturing birds in flight is one of the most difficult of photographic exercises. With large birds, see some of my kite photographs for example, a fast shutter speed (Tv = 1/1000 th second), a steady hand, a long lens (400 mm for handheld work - 560 mm at a stretch), good light, and continuous shoot mode are the basics. Large birds move quite slowly and you can focus on them as they fly past. For small birds, however, there are further difficulties to overcome.Let me start with a bird, a blue tit, definitely not in flight. I'm using this to show that a good camera, a go

I did some reading up on the matter last night and, apparently, some species, the parents will eat itΒ (the entire sac) (which, as you can imagine, can get to be a Lot of repetitions; this is, after all, birdie versions of diapers vomits ..
Anyway... apparently, with the babies that young their systems can't fully digest their food, and, (much the same as with rabbits) nutrients are contained in that (poo sac) . Committing this gross act, also allows for the parents to spend more time near the chicks, keeping an eye on them; rather than have to fly off and dispose of the diapers; taking their attentions away, and increasing the chances for predators..Β
But David... did you know... Not only does the chick do this wonderful trick, but it first turns it's back to the parent/s and poop/shoots it right At the parent?Β
Now That - is what I call co-operation!Β Β all for the birds, of course .. Β Β Β

I certainly didn't know the last part, Linda, but I knew some species of birds consume the output. In terms of evolution, these different behaviours represent different species finding different ways to maximise their survival, even if we find some such rather revolting.

yep yep, learning the 'whys', tho nauseating, is nonetheless very interesting! (and perhaps, not As gross as I first was thinking.. in that, recalling my neighbor's son's rabbit... it's poo didn't really seem to have much of a smell to it at all... the same with the birds, I'd reckon. Makes a lot of sense.. still... I'm very glad that I'm not a rabbit.Β nor a bird..
