Subject: (How) Are Birds Affected by Volcanic Ash?
From: Devorah Bennu <birdologist AT YAHOO.COM>
Date: Tue, 20 Apr 2010 11:02:42 -0700
hello everyone,
as many of you know, april is the peak of the spring bird migration. if you've
followed the news at all, then you are aware that a volcano has been erupting
in south-central iceland and has sent an ash plume over much of northern
europe, including where i live with my parrots. the frankfurt airport was just
reopened a few hours ago, but the ash clouds are thickening once more,
obscuring the nearby hills, so who knows how long aircraft will
continue flying
into germany. anyway, all that said, one of my readers emailed about how
volcanic ash affects birds. i have spent the past two days researching this
question because there are no studies about this issue in birds (that i was
able to find), and i am sharing my thoughts and findings in the hopes that i
can help others who are faced with this problem now, or might be faced with it
in the future (i was a kid when Mt St Helens erupted and dumped eight
inches of
ash onto the area i lived in, for example).
here's the essay;

if anyone knows of studies in birds of any species on this topic, i'd love it
if you send the reference, or better yet, send me the PDF!
cheers,
