Black-throated Green Warbler

Black-throated Green Warbler (Dendroica Virens)  is a migratory song bird. They mainly nest in east of North America and central and east of Canada during summer and migrate back to their wintering ground in central America and Mexico. They start their spring migration as early as mid March and reach Georgia by late March and early April.

I stopped by Kennesaw Mountain Battlefield Park five times in spring and saw and heard this warbler everywhere. Unfortunately, there was just no way for me even to have a nice look at them since they foraged on top of trees and hardly came close to gound. And we all remember that "warbler's neck" we got. I just wished I could have one photo of them, just one. My wish came true when I decided not to go to Costco Saturday afternoon and stayed home, birded around my backyard in stead.

Golden Crowned Kinglets (click link to see photo and sound) were the first drew my attention. Suddenly, I saw this bright yellow faced bird with a black throat. I quickly grabbed my binocular and surprisingly found out it was a male Black-throated Green Warbler foraging high on top of a pine tree. He was gleaning on tips of pine branches for insects. After running inside and returning with camera, this warbler was no where to be found. I was really disappointed and thought I just needed to wait for a while to see. Something I learn from being a birder is that I now have more patience with things. I believe everything in this world happens with it's own reason. We can not force nor can we rush things to happen. I told myself if I miss this bird this time, there is always another chance to see it, most likely will be the next year during spring migration.

While walking back towards house with disappointment, I noticed a movement on a lower branch of another pine tree. I screamed "it is the same bird"!! Camera was on and I could not think anything else but clicking my camera shutter button. I managed to take few pictures, not so perfect though. I was happy to have few images of this Black-throated Green Warbler to share with readers.

Habitat and Conservation
Black-throated Green Warbler appears in mixed wood forests at between 80 to 130 years of coniferous forest, such as spruce, fir, and pine. They are mainly insectivorous and they sometimes take berries during migration. During breeding season, they consume a lot of butterflies and moth larvae and they also eat beetles, flies, ants and wasps. Male normally returns to the breeding ground few days before female to reclaim their territories. Their nest is cup shaped and can be found on a branch near a tree trunk..

Deforestation and forest degradation in North America not only endangers Black-throated Green Warbler, but seriously effects many songbird species. Forest regenation will not have time to produce enough growth to reach its maturity. We hear them singing beautiful songs from top of tree canopies, see their vivid color from our backyard and our future generations might not have chance to even know this bird if we don't care. The easiest thing we can do now is to protect our forest resources by reducing log cutting and lumber purchase by

1. using green products and renewable resources, such as Bamboo products,
2. using recycle paper made products,
3. using both side of your printing papers before you dump them into your trash bin,
4. using recycled rubber products (see link below),
5. if you have to use wood for home projects, try buying pressure treated lumber (they last longer and termite free, theoretically). In such a way, hopefully, your wood project will last longer.

Final note: do you know Bamboo is the fastest-growing plants on earth!I found these sites are informative and educational and I hope you can check them out!
