Jaimi Butler, Badass
I’m convinced that my friend Jaimi Butler has been, and continues to be, our most persistent and effective voice in the battle to save the disappearing Great Salt Lake. When it comes to the lake she’s a highly knowledgeable, passionate and eloquent firecracker and I love that in her.
Male Loggerhead Shrike Feeding His Mate
Male Loggerhead Shrikes feed their mates beginning with the formation of pair bonds in early spring and such behavior continues throughout the incubation and nestling periods.
Enveloped By Shrikes!
These young birds loved clamoring around on the hood of my pickup. They would look at their reflections, pick at smashed bugs and just generally act like inquisitive kids. It wasn’t unusual to hear a bird clicking about on my roof at the same time one of its siblings was on my hood.
Juvenile Loggerhead Shrike Take-off
Many of the young Loggerhead Shrikes on Antelope Island have now fledged and are learning the ropes. They’re ornery, fun, fierce and fearless. Twice I’ve had one almost fly into my open pickup window, another one very nearly landed on my lens hood sticking out a window and yet another landed on the pickup itself.
Birds, Spiders, Brine Flies and Mercury Contamination on Antelope Island
Last Sunday I found this Northern Shrike on Antelope Island enthusiastically singing away as if spring were already in full bloom. Their predatory habits and interesting behaviors make them a favorite species for me but when I got home that day I read an article in the Salt Lake Tribune that made me wonder just how healthy their populations near the Great Salt Lake really are. North end of Antelope Island, 2/5/12 The reason for my concern is a bit complex but I’ll summarize: For over 100 years smelting operations have been responsible for high levels of elemental mercury in the Great Salt Lake and its sediments. Microorganisms in the lake convert the mercury to methyl mercury which is the toxic form of the element that can be absorbed by tissues of living things. Brine fly larvae living in the lake then absorb the methyl mercury and when they hatch the adult flies are consumed by spiders living in the vegetation around the lake. Finally, those spiders are eaten by the many bird species living and nesting along the shoreline. But very little is known about the movement of mercury compounds through Great Salt Lake ecosystems, including the possible effects of toxic methyl mercury on birds so Westminster College’s Great Salt Lake Institute was recently awarded a $250,000 grant from the W.M. Keck Foundation to study its possible effects. Antelope Island causeway, 8/29/11 The number and total biomass of brine flies in late summer around the lake literally boggles the mind but this shot should give you some idea. It was taken in late August of…
