Dr. Wilson, I will take a crack at responding to your query. In 2002-5, in 
reaction to the news stories on West Nile virus (WNV) and bird deaths, there 
was a fairly active effort among the Colorado populace to report dead birds to 
local health departments. Consequently, many birds were tested, and maps of 
WNV-positive counties based on avian mortality surveillance were frequently 
updated on the Colorado state health department website (and on CDC and USGS 
websites that presented national data). At the time there was some (limited) 
discussion of the relationship between WNV and avian mortality on the COBIRDS 
listserve. However, with the media hype, public participation (outside of the 
COBIRDS listserve) in the avian mortality surveillance project was substantial 
and productive.
 

After 2005, media attention to WNV waned, and with diminishing public 
resources, State and County health departments could not use the data derived 
from avian mortality surveillance to alter their disease prevention programs 
significantly, so the program dissipated, with the exception of a few small 
CDC-sponsored projects in collaboration with a couple of County health 
departments and several wildlife and raptor rehabilitation programs. I was the 
Principal Investigator of these projects, some of which are ongoing. In fact, I 
will provide information on such a project at the upcoming State Zoonoses 
Conference in Denver on April 14th.

 

There has also been a little bit of discussion on the list serve of avian 
diseases such as H5N1 avian influenza and House Finch conjunctivitis, but in 
the grand scheme of things, I don’t think the birding community plays a big 
role in finding sick and dead birds and getting specimens to testing facilities.

 

This could be due to a few possible explanations, including (but not limited 
to):

1.     Birders are aware that handling sick or dead wild animals requires a 
permit

2.     Birders that do turn in carcasses to authorities are more likely to 
submit specimens to museums rather than health departments, because of the 
(largely correct) assumption that the specimen will be put to better use in the 
museum.

3.     The common message from Health Departments that specimens will no longer 
be tested is frustrating to concerned citizens

4.     Serious birders (i.e. the several hundred members of this listserve) do 
not constitute a large enough portion of the general public to find enough dead 
or sick birds to get the attention of the health authorities.

5.     The majority of dead birds found by the public are a result of car 
strikes, window kills, nest mishaps and other common causes that do not present 
a public health threat

6.     H5N1 avian influenza has not yet been detected in North America

7.     Many serious birders (e.g. listserve members) are more interested in 
birds as a recreational distraction rather than for conservation, and thus pay 
a lot more attention to living birds than to dead birds.

8.     Even the conservationists within the birding community mostly (and 
rightly) believe that the major threats to bird populations do not come from 
disease but rather from habitat loss and degradation of a healthy ecosystem due 
to human activities

 

With all that said, I do believe that testing apparently innocuous single 
carcasses of birds and other wildlife could be a very important means of 
pathogen discovery and help prevent a potential epidemic of something novel 
(like WNV when it first arrived) or even a potentially catastrophic pandemic 
(like the threat of a mutated virulent zoonotic flu virus, such as that 
presented by H5N1 avian influenza). But to make such surveillance efforts 
worthy, there needs to be buy-in from the public (birders could definitely help 
in this regard) and from well-funded government public health agencies (these 
don’t currently exist, and it seems like they won’t exist for the foreseeable 
future). 

 

There are additional complexities that could be discussed regarding the 
reporting of dead birds, and testing carcasses for disease, but I probably have 
said enough for this forum.

 

I would be happy to discuss these issues further outside of COBIRDS.

Subject: [cobirds] Wild Avian Disease Surveillance...
Importance: High

 

Greetings everyone,

 

I am a pediatrician by training who lives now permanently in the West Slope of 
Colorado.  My presence in this group is from the standpoint of integrated 
operational biosurveillance- in other words, the pan-species monitoring of 
infectious disease (or "biological") events that may represent an emerging risk 
that extends beyond the primary species (e.g. birds) and may extend to other 
species such as equines, swine, livestock, or most importantly, humans.

 

I've attached my bio below for background.  Our team was heavily involved in 
West Nile virus surveillance, detection and warning of H5N1 avian influenza 
worldwide, and the recent emergence of pandemic H1N1.  So, avian disease is of 
ongoing key interest to us.  My purpose here is to support your efforts in the 
protection of Colorado's avian wildlife and by extension, protection of 
agricultural and companion animal species, with an eye to disease that could 
directly affect humans.

 

My question to the group is what did you see during the emergence of West Nile 
in the early 00's?  Was this group active in noting bird die-offs?

 

Cheers,
