About two weeks ago I found an adult Loggerhead Shrike perched on a lichen covered rock in northern Utah a good distance from the road that I was on. This small raptor-wanna-be was busy calling and singing<\/span><\/a> when I spotted it.<\/p>\n

Given that it is their breeding season here in Utah this shrike may have been trying to find a mate.<\/p>\n

But will this shrike find a mate?<\/strong><\/h2>\n

I have concerns about that. Since I moved to Utah in 2009 I have seen the numbers of Loggerhead Shrikes drop significantly. In areas where I used to see twenty to twenty-five Loggerhead Shrikes I am now lucky if I find even one. I work hard to find this species now. It wasn’t always that way.<\/p>\n

Over the winter I may have photographed this particular shrike. It wasn’t all that far from where I consistently found a single Loggerhead Shrike throughout the coldest months of the year. That shrike was always alone. I never found another one nearby. There wasn’t another shrike near this one either.<\/p>\n

Without any doubts I know that my observations of Loggerhead Shrikes are far fewer than they used to be and that I am not the only person who has wondered about a decline in their population in northern Utah. Other local birders and bird photographers have mentioned that they too are seeing fewer Loggerhead Shrikes than they used to see.<\/p>\n

Seeing fewer Loggerhead Shrikes worries me. I wonder if they are being impacted by our drought and climate change or if both of those issues have caused a reduction in their prey in Utah. I truly don’t know. What I know is that there are fewer of them to be found in northern Utah than there were just five or six years ago.<\/p>\n

And that isn’t good news.<\/strong><\/h2>\n

According to allaboutbirds.org<\/span><\/a> this species is in steep decline.<\/p>\n

Loggerhead Shrikes are still fairly numerous in some areas (particularly the South and West), but their populations have fallen sharply. Between 1966 and 2015, the species declined by almost 3% per year, resulting in a cumulative decline of 76%, according to the North American Breeding Bird Survey.<\/p>\n

The species\u2019 decline coincides with the introduction and increased use of chemical pesticides between the 1940s and the 1970s, and may result in part from the birds\u2019 ingestion of pesticide-laced prey from treated fields. Other likely causes of population decline include collision with vehicles, urban development, conversion of hayfields and pastureland, decimation of hedgerows, habitat destruction by surface-coal strip-mining, and altering of prey populations by livestock grazing.<\/p>\n

In northern Utah unchecked urban sprawl, the use of pesticides and other habitat destruction may be only part of the cause for the decline in the numbers of Loggerhead Shrikes that I am seeing.<\/p>\n

We need to do more to protect Loggerhead Shrikes, other birds, and the entire natural world.<\/p>\n

Now.<\/p>\n
