Scissor-tailed Flycatcher Nest...in Mississippi!


My first Scissor-tailed Flycatcher sighting occurred several years ago while I was waiting at a bus stop in Fayetteville, Arkansas.  I’ve seen these birds countless times since then, and even noticed some recently fledged young from time to time.  That was in Arkansas, though.  The species is rare where I now live; any Scissor-tails that show up east of the Mississippi River tend to garner a lot of attention from birders.  So when a pair of Scissor-tails nested in a rural part of Lowndes County, MS, south of Artesia, back in spring/summer 2015, I was thrilled.

Scissor-tailed Flycatcher in Lowndes County, Mississippi
I went out to the area with a couple of my family members, hoping to see the birds and their nest.  It wasn’t too difficult to spot the adults.  With their gorgeous streamer-like tails, loud calls, and exuberant foraging behavior of sallying out to catch flying insects, Scissor-tails are the polar opposite of inconspicuous.  And their habitat, wide open fields with a few trees and shrubs, doesn’t provide much in the way of concealment.  That said, I suppose that trying to find this species in Mississippi really can be a bit like looking for a needle in a haystack, given how many farms and fields there are to search.

The birds had built a nest very high up—probably a good 80-85 feet—on a cell tower.  The species typically builds nests at much lower levels than this; a study in Texas (Nolte and Fulbright 1996) showed that the average nest height was a little over 9 feet, or 2.8 meters.  The highest nests found during field research in Texas in the late 1940s were built 26 ft., 10 in. up on the cross-arm of a telephone pole (Fitch 1950).  The author, Frank Williams Fitch, Jr., referred to these telephone pole nests as “unusual.”  I wonder what he would have made of the cell phone tower nest near Artesia!  To be fair, I doubt that many mid-20th-century field ornithologists had any inkling of how drastically the landscape would change as a result of technology.

Maybe the Lowndes County flycatchers simply felt more secure at the tower than they would have if they had nested in a shrub.  Aerial predators wouldn’t have had any trouble accessing the nest, of course, but I expect that the height would have deterred most other potential nest raiders.  The nest is in the center of the photo below.  You can just barely make out the grasses, stems, and roots hanging down from the metal bar.

Scissor-tailed Flycatchers lay 3-6 eggs, but I knew that I wasn’t going to be able to see any eggs from the ground!  Nest cameras certainly would’ve been helpful here. 
 
Can't really see anything...
The December 2016 issue of The Mississippi Kite contains a mention of these nesting Scissor-tails (Vol. 46, No. 2, p. 19).  It says that they were observed from April 22 to July 17.  This would have given them ample time to build the nest (a process that takes a few days), deposit the eggs (females lay one a day), incubate their eggs (which the females usually take about 14 days to do) and raise the nestlings (a task for both parents that averages 15.4 days).  Sometimes Scissor-tailed Flycatchers take up to four weeks’ time between nest-building and egg-laying.  I can only assume that there must be some benefit (or at least no drawback) to taking things easy, or surely the birds wouldn’t do it.  On the other hand, maybe Scissor-tails are using most of this “extra” time to defend and secure their territory, and aren’t being lazy at all.  It’s worth considering, right?

To conclude, here are some better-quality pictures of Scissor-tails that I took at a couple of different locations in Arkansas:
