What Happened To Most Of The Pronghorn On Antelope Island?
I don’t know a definitive answer to that question but I think I have a pretty good guess. (4 photos)
Pronghorn Fawn Running To Mama
With his long legs seeming to go every direction except the direction he was running.
Odd Growths On The Face Of A Pronghorn
Earlier this month we encountered an unusual male Pronghorn on Antelope Island. Close inspection through our lenses revealed something that caught our attention – this animal had two strange-looking projections apparently growing out of the top of its muzzle. .
The Trouble With Harems
Mia and I spent most of this week on a camping/photography trip to Flaming Gorge, Utah and we had some wonderful photographic opportunities with pronghorns. We camped on an isolated peninsula and it happened that a buck pronghorn was using the topography of the peninsula to help him keep control of his very large harem of females. The herd consisted of the lone buck and many females – both adults and juveniles. The male was in full rut and frantic to keep his does together and prevent several other males from running off with them. Does have varying mating strategies. Some does, called “sampling” females, will visit several males during the breeding season if allowed to do so. Others, referred to as “inciting females”, behave as sampling females until they come into estrus when they move off from the males which incites fights and aggressive competition between the males. These females always immediately mate with the winning male. Some females employ a third strategy where they join a single male and remain with him throughout estrus – these does are called “quiet” females. Canon 7D, 1/800, f/5.6, ISO 640, 500 f/4, 1.4 tc This poor buck was trying to control at least 28 females and was struggling mightily to do so. One evening we were at the bottom of a string of small hills just as the sun was setting (thus the warm, golden light in these photos). The buck and his females were strung out on the crest of several of the hills and one of the does was giving him a hard time by…
Antelope Island Potpourri
My last few visits to Antelope Island have yielded a mixed bag of bird and mammal photos that I enjoy so I thought I’d share a little of what it’s like to experience the wildlife out there during late spring. Canon 7D, 1/2000, f/6.3, ISO 500, 500 f/4, 1.4 tc This take-off pose is one I’ve been after for some time so I was glad to get it from this Loggerhead Shrike, despite the foreground twig in front of the right wing-tip. Canon 7D, 1/2500, f/6.3, ISO 500, 500 f/4, 1.4 tc I believe this to be the same bird as in the previous photo. It had captured what I think was one of the Ichneumon wasps and toyed with it a while before dropping it. I was happy to get the wasp unobscured by the branches or the birds toes as it fell. The shrike watched where it fell and retrieved it. Canon 7D, 1/2000, f/6.3, ISO 640, 500 f/4, 1.4 tc There are presumably many pronghorn fawns on the island this time of year but I’ve found it difficult to get close to them or even to spot them at a distance – probably partially due to their instinctive behavior of lying low in the tall grasses much of the time. This one was in a playful mood and spent several minutes romping through the grass around its mother. Canon 7D, 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc This is the same fawn a few minutes later, just after nursing. …
The Coyotes and the Plucky Pronghorn
Yesterday Mia and I were witness to quite the little drama on a trip to Antelope Island to photograph birds. It all started when we noticed the frantic calling of a Long-billed Curlew which flew over us several times in obvious distress. Canon 7D, 1/2500, f/6.3, ISO 640, 500 f/4, 1.4 tc At first we didn’t know what was causing all the ruckus but soon Mia spotted this coyote. A couple of minutes later we noticed a second coyote nearby. We suspect that the curlew had a nest in the vicinity and it was disturbed by the foraging coyotes. Soon both coyotes disappeared into a ravine but we hung around hoping for more flight shots of the curlew. Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc Then, almost a quarter-mile away, we spotted the coyotes again but this time a doe Pronghorn (at least I think it’s a female and not a young male) had entered the scene. There was obviously going to be a confrontation and at first I assumed that the coyotes would be the aggressors but I was quickly proven wrong. Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc This doe had pluck! After a few seconds of staring each other down the pronghorn charged the coyote on the right. Canon 7D, 1/1600, f/7.1, ISO 640, 500 f/4, 1.4 tc That coyote beat a hasty retreat but the teamwork the coyotes showed was impressive. They always stayed a short distance apart and whenever the doe would…
