Flaming Gorge Osprey – An Experiment That Worked

We returned home Thursday after spending three wonderful days camping at Flaming Gorge in NE Utah. This is very close to the view we had on most mornings from our campsites (two of them), though this image was taken the morning before the Osprey photo, below. As you’ll see, the lighting conditions were dramatically different…

Flaming Gorge Osprey

The Osprey is a species that I’ve only had a handful of opportunities with but last spring I found a cooperative nesting pair at Flaming Gorge. In my mind this is a true miracle species because it has arisen Phoenix-like from the ashes of its own demise.  During the 1950s-1970s their populations crashed dramatically, largely due to the effects of DDT and other persistent pesticides in the environment which caused severe eggshell-thinning and poor hatching success.  But when those chemicals were banned the Osprey made a miraculous comeback and today their numbers are approaching historical highs. Part of the reason for that success has been the widespread use of artificial nesting sites.   In some areas of North America, 90-95% of all nesting pairs choose these artificial sites over natural ones.  The nest of this mated pair was on a pole installed for that purpose close to Flaming Gorge Reservoir.    1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, cloned out a piece of nest platform, not baited, set up or called in This is most likely the male of the pair (less conspicuous breast band) bringing a small fish in to the incubating female on the nest platform.       1/2500, f/7.1, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in  I believe this to be the female coming into the nest.       1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc, canvas added, natural light, not baited, set up or called in  When the male would bring its mate a fish…

An Osprey, A Fish And A Thieving Magpie

Yesterday Mia and I returned from a three day camping and photo trip to Flaming Gorge.  We had great weather for most of our time there and as usual the scenery and ambience were awesome.  At an elevation over 6000′ many of the birds that we usually see there apparently haven’t arrived yet but we spent some quality time with a pair of nesting Osprey – a species that I’ve had little luck with in the past.    1/2000, f/5.6, ISO 500, 500 f/4, 1.4 tc This pole with all the attached ugly hardware was within a few feet of the nesting platform and early one morning this Osprey landed on the pole with a freshly caught fish.  At first I figured that this bird would deliver the fish to its mate on the nest (I have a lot to learn about this species) but it didn’t.  It’s intention was to eat the fish itself but as you’ll see, those plans were delayed by an interloper.     It didn’t take long for this Black-billed Magpie to show up and torment the rightful owner of the fish.  This Osprey removed and dropped the intestines in pieces and it seemed obvious to me that the magpie had learned that particular feeding pattern and came looking for  tidbits that had landed on the wires below the Osprey.  Here you can see one of those bits in the beak of the magpie that it had picked off of the metal above its head.   So far the Osprey doesn’t seem too…
