The Frustrations of Unnatural Perches

Most bird photographers prefer their subjects to be on natural perches.  We are, after all, nature photographers.  The definition of just what is “natural” becomes a slippery slope for sure but for my purposes I’ll define a natural perch by exclusion – it does not include buildings, telephone poles and wires, chunks of concrete, signs, or most anything else that is obviously man-made. Now for my exceptions.  Some objects that are man-made and have a “rustic” quality are often acceptable.  Weathered fence posts, old barns and rusty barbed wire would be examples.  One of the major frustrations of bird photographers is to be able to finally get close to a beautiful subject in good light but the bird has chosen an ugly or inappropriate (for us) man-made perch.  It is typically very difficult to approach many bird species close enough to get excellent detailed photos, even with big expensive lenses.  So it can be aggravating in the extreme to finally get close enough but the bird has chosen an unappealing perch.  Some folks choose to largely avoid this problem by shooting at “setups” where the bird has been unnaturally lured into an artificial situation by provided food with attractive perches arranged close by.  To many of us this is not nature photography but more like studio or zoo photography.  Good bird photography ain’t easy.  If it were it wouldn’t be nearly as satisfying when I do finally get the shot I’m after – even though the pursuit has often been frustrating.  Below are some of the situations where I’ve been frustrated by these unattractive, unnatural perches.        Most bird photographers know…

American Kestrels Rejecting Intestinal Tract of Prey

  Several times I have photographed American Kestrels discarding the intestinal tract of their prey.  The prey has always been a vole or mouse when I’ve seen it happen, though it may occur with small birds also.  I was surprised by this behavior.  Every time I’ve seen it happen has been during our harsh winters when I would assume every last morsel of food would be significant for their survival. Below is a series of photos where a female American Kestrel demonstrates the behavior with a vole kill. Female kestrel begins to pull small intestine out of a vole And deliberately drops it      The cecum? is discarded:  the intestine is still attached to the body and hanging down the side of the post   She pulls more intestine out of the vole   Breaks it loose from the body      And deliberately drops it to the ground   Finally, she pulls out the last of the small intestine, which she also dropped I know of others who have seen similar behaviors in other raptors – a variety of hawks and Osprey.  Several theories to explain it have been mentioned by bird photographers and others who have seen my photographs.  Among them: “These organs are filled with potentially harmful bacteria”.  Then how are many raptors, owls for example, able to consume their prey whole without harmful effect? “These organs are filled with food of low value to the kestrel (vegetative matter). Why fill up on carbs when it’s protein you need?  Begs  the question – Would they also discard intestines of insectivorous birds?  I don’t know……
