Flock of Red Crossbills highlight from recent Roan trip

By

I am seeing Green Herons on almost every visit I make to any local body of water. In the last week I have seen this small heron at the pond at Erwin Fishery Park, at Musick’s Campground on South Holston Lake in Bristol and from the board walk over the pond along the linear trail near Erwin’s Riverview Industrial Park.

The Green Heron at Erwin Fishery Park was stalking dragonflies along the edge of the pond and appeared to be having good success at capturing these winged insects. I saw the heron catch and eat several dragonflies while observing it.

A few warblers and other birds not attracted by feeders are starting to make appearances in my yard. A noisy family of Blue-gray Gnatcatchers, a female Hooded Warbler and a gorgeous male Northern Parula all showed up in the last week. I’m sure it won’t be long before other warblers visit the yard as they migrate farther south for the winter.

My mother and I made a trip to Carver’s Gap on Roan Mountain on Saturday, Aug. 3. We hadn’t even gotten out of the car when my mom noticed some Red Crossbills perched in the upper branches of some of the Fraser Firs near the parking area at Carver’s Gap. We continued to watch the crossbills and counted a total of seven birds, although the flock may have consisted of a few additional members.

The observation of the Red Crossbills allowed me to add this bird to my 2013 list as Bird No. 170 for the year. It’s going to be a challenge to get those other 30 species to reach the 200 mark for the year, but I am looking forward to it.
The crossbills were all busy ripping apart the new cones on the firs to get at the seeds. Feeding on cones must be a messy business, because the feathers around their heads appeared matted in a few spots. I had never thought about it, but these birds must constantly get pine resin on their feathers as they use their crossed bills to pry open cones.  One of the male crossbills made quick work of several cones, using his bill to take them apart with esquisite precision. He had the process honed into a science.

The Red Crossbill, known by the scientific name Loxia curvirostra, is a member of the finch family, which includes such well-known feeder-visiting birds as American Goldfinch, House Finch, Purple Finch and Pine Siksin. In Europe, the species is known by the name Common Crossbill.

Crossbills have distinctive beaks, which cross at the tips, enabling them to skillfully extract seeds from conifer cones and other fruits.

Red Crossbills are rather nomadic and breed in areas with an abundant crop of cones. These birds may wander widely between years to find a good cone crop. Perhaps because of this year’s wet weather, there’s a bounty of new cones on the trees at Carver’s Gap, so it has been a good summer to look for Red Crossbills.

For many years, this was one of my “nemesis” birds. No matter how hard I tried, I kept striking out in attempts to observe the species. I made many trips to Unaka Mountain and to Carver’s Gap on Roan Mountain to look for this bird before I finally got a good look at a pair of birds picking up grit from gravel at the edge of the Carver’s Gap parking lot.

Experts debate how many species of crossbills exist, but the current consensus is that there are five species worldwide. In addition to the Red Crossbill, the White-winged Crossbill lives in North America but is an even more rare visitor to Northeast Tennessee.

The other three species are the Parrot Crossbill of northwest Europe and western Russia, the Scottish Crossbill of the Caledonian Forests of Scotland and the Hispaniolan Crossbill of the Caribbean island of Haiti and the Dominican Republic.

After observing the crossbills and taking several photos, we made the ascent to the grassy balds to look for other birds. I held some hope of finding a Vesper Sparrow, but these small birds never made an appearance.

I did observe Common Yellowthroats, Golden-crowned Kinglets, American Robins, Gray Catbirds, Cedar Waxwings, Dark-eyed Juncos and Northern Ravens during my hike on the balds.

Speaking of hummingbirds, Shirley Lewis in Elizabethton called me to ask how to cope with overwhelming numbers of yellowjackets at her hummingbird feeders.

There’s actually a nifty item that can help people cope with hornets, bees and yellowjackets trying to sip at sugar water feeders.

I suggested she look into purchasing some “bee guards” for her feeders or obtaining a feeder already equipped with these guards, which are basically yellow plastic mesh cages that fit over the feeder ports.

Moving the feeders is worth a try. The hummingbirds will likely re-locate the feeder while insects like yellowjackets may not.

I did some research and discovered that another alternative could be to lower the ratio of the sugar water mix to 1 part sugar to 5 parts water. The weaker solution will probably not appeal to bees and wasps but would probably still hold the interest of hummingbirds.

From past experience, I know that yellowjackets can be a hassle

at feeders. I hope some of these suggestions might work.

I received an email this past week from Crystal Miller about a fascinatin

g observation of Bald Eagles on Friday, July 26.

“I was rafting down the lower Nolichucky River, in Tennessee, just past the Devil’s Looking Glass,” Crystal wrote.  She was rafting with five other people when they saw a huge nest on the right side of the river. She said the nest was fully occupied, except for one parent circling overhead.

“The other parent was a few feet from the nest, while other younger eagles were closer, inside and around the nest,” she wrote. “We paddled against the current as long as the river would allow before we succumbed to the river.”

Crystal said others on the raft took pictures of the eagles and the nest.
“None of the younger eagles had white, or bald heads, but one I noticed had incredibly large legs,” she wrote.

She described her rafting adventure as the “best trip ever.”

Crystal also shared that her mother was born and grew up along the river, and that her grandmother still lives in a house near the river.

“That eagle nest made me happy,” she concluded.

Crystal’s sighting of this family of eagles is more evidence that this once endangered National Bird is indeed fully recovered and thriving.

Earlier this year, I learned of reports of a Bald Eagle nest in Unicoi County near the Devil’s Looking Glass. It’s very likely Crystal’s story provides more evidence that the nesting was successful.

Other eagles also successfully nested in Sullivan County and Washington County. A nest at Wilbur Lake here in Carter County, unfortunately, was destroyed during a powerful storm this past spring.
