3 Facts about Turkeys

Thanksgiving is right around the corner and in preparation for the holiday season I've decided to list a few facts I found interesting about turkeys (Meleagris gallopavo).

1.  While most of us are familiar with the "gobble" sound made by turkeys, these birds also make a host of other calls.  According to the Cornell Lab of Ornithology Website, male turkeys "gobble" to attract mates, females and males "purr" while on foot, and courting males produce a "chump" sound which is not well understood (2014).  If you're curious about how these actually sound as well as other bird calls I highly recommend you visit the Cornell Lab page here.

2.  Fun fact, Benjamin Franklin wanted turkeys to be our national symbol, not the bald eagle and lamented the choice. an Article in Slate Magazine, by Nicholas Lund (2014), cites a letter from Franklin stating, 

  "For in Truth the Turkey is in Comparison (sic. eagle) a much more respectable Bird, and withal a true original Native of America. He is besides, tho’ a little vain and silly, a Bird of Courage, and would not hesitate to attack a Grenadier of the British Guards who should presume to invade his Farm Yard with a red Coat on."

3.  Every year the President of the United States pardons a turkey....... This year the lucky bird who won't be for dinner is from Ohio.  Read about it here.

Nature Deficit Disorder

Recently, a number of documentaries have been published alleging that teens and children today lack adequate exposure to nature.  The term, "Nature Deficit Disorder", first stated by Richard Louv in his book, "Last Child in The Woods" has become the phrase associated with the lack of outdoor play in children.  According to Louv, "Kids who do play outside are less likely to get sick, to be stressed or become aggressive, and are more adaptable to life’s unpredictable turns." (Egan, 2012).  What sort of evidence supports going outside more?  Studies completed by Atchley & Strayer (2012) on individuals going on hikes state: 

"Our results demonstrate that there is a cognitive advantage to be realized if we spend time immersed in a natural setting. We anticipate that this advantage comes from an increase in exposure to natural stimuli that are both emotionally positive and low-arousing and a corresponding decrease in exposure to attention demanding technology, which regularly requires that we attend to sudden events, switch amongst tasks, maintain task goals, and inhibit irrelevant actions or cognitions"

  Despite an apparent correlation between nature and increased cognitive advantage the study failed to  conclude if exposure to nature or decreased use of technology resulted in a cognitive advantage.  Do you think kids aren't exposed to enough nature?  

Below are two trailers for documentaries addressing "Nature Deficit Disorder".

Trailer 2:  "Play Again"

New invasive species found in Pennsylvania

Invasive species can be destructive forces in natural ecosystems and agricultural settings.  Recently, a number of counties in Pennsylvania have been put under quarantine as a non-native insect species was detected. The insect species in question, commonly known as the spotted lanternfly (Lycorma delicatula) , is native to China and southeast Asia.  The insect belongs to the Order Hemiptera, and is in fact, not an actual fly but a type of planthopper belonging to the family Fulgoridae. According to Dara (2014), "Spotted lanternfly feeds on a variety of host plants including fruit trees, ornamental trees, woody trees, and vines.  Apples, birch, cherry, dogwood, grapes, Korean Evodia, lilac, maple, poplar, stone fruits, and tree-of-heaven are among more than 70 species of hosts attacked by this pest."  This wide host range could become problematic for a number of agricultural crops if the spotted lanternfly were to become established in the United States.
