Do Animals ‘Drink’ Intentionally?

A link to the following article was in my mail yesterday.  The article is interesting however, I don’t think it really gets at what might be underlying causes of birds imbibing a little too much or a little too frequently….

James MacDonald.  2014.  When Birds Drink Too MuchJSTOR Daily, January 1,4 2015.

 

There are two articles cited by the above mini-article.  I think that they are important and can be read online without any extra cost.

Frank Wiens, Annette Zitzmann, Marc-Andre Lachance, Michel Yegles, Fritz Pragst, Friedrich M. Wurst, Dietrich von Holst, Saw Leng Guan, and Rainer Spanagel.  2008.  Chronic intake of fermented floral nectar by wild treeshrews.  PNAS, Volume 105, No. 30, pages 10426-10431.

Treeshrews?  Waxwings?

My thoughts on this are going towards the caloric intake in fruits and berries that are fermented or are in the process of fermenting.  It seems to me that it might be higher than when the fruits and berries have just freshly ripened.

Is it just the birds or do other creatures like a little drink now and then too?

Reading a bit further and another thought occurred to me!  Higher caloric intake for wildlife, just before winter sets in, would be useful for survival.  Putting on a little weight to get through the cold dark nights.  Can the fermentation of fruits provide other contributions to survival?

So, if the intoxicating fruits and berries are a good thing, why are some birds overdoing it?  Now?  Could it be that there is less competition for these yummy morsels?  Fewer birds equals more party favours?

Jennifer A. Howard.  2014.  The Lesser Coverts of Game BirdsBooth, Volume 6, No. 2, Page 1-2.

Probably not the best answer to my question but, a very good short story!  One that has me thinking a bit further off-track than usual.  I will come back to this story for another post.

And then, there are people….

O’Keefe, and Janette Brand-Miller.  2005.  Origins and evolution of the Western diet:  health implications for the 21st centuryThe American Journal of Clinical Nutrition.  Volume 81, pages 341-354.

And, because we can think of other things to do with ethanol products…

Veeranjaneya Reddy Lebaka, Hwa-Won Ryu, and Young-Jung Wee.  2014.  Effect of fruit pulp supplementation on rapid and enhanced ethanol production in very high gravity (VHG) fermentationSpringerLink.  doi:  10.1186/s40643-014-0022-8

 

~~~

And thinking along these lines… maybe we need to look at chronic diseases that may have some beginning in the foods that are available to us now as well as those that we choose to eat a lot of and, without competition, possibly eat a little too regularly – much like the small woodland creatures and birds in the first few articles.

Your thoughts are important to me and to continuing this as a discussion.  Please comment….

 

 

 

 

 

Arctic Pollution from Unexpected Sources

A summary of the article, Sea Birds Fly Pollution to the Arctic, by Andreas von Bubnoff.

My Precis

We know that pollution is being carried to the Arctic by wind and tides and now we also know, through scientific investigation and the testing of lake water, that pollution is carried into the Arctic by migrating birds.

~~~

My Precis Expanded:

Arctic lakes that are used by birds such as Northern Fulmars (Fulmarus glacialis) have been found to contain higher concentrations of toxins such as mercury, DDT, and hexachlorobenzen (HCB) than lakes with lower bird populations. To determine the extent that birds are bringing pollution with them, eleven Arctic lakes, located both near and at a distance from, nesting sites were tested for chemical pollutants. Some of these lakes were found to have very high mercury concentrations.

Birds eating contaminated prey or carrion become contaminated themselves as chemicals such as HCB, DDT and PCBs collect in an animal’s fatty tissues. These chemicals then pass on to other predators when the contaminated meat is eaten. Indigenous peoples living in the Arctic and relying on game for food are eating contaminated animals. “Mercury and PCBs can cause immune system dysfunction, adverse neurological effects and IQ deficits.”

Wind and sea currents are major sources of pollution in the Arctic. The best way to fix this problem is to prevent more contamination “from entering the environment in the first place.”

I found the original article through a search using Google.
