I studied the congregation of gulls at the south end of Irondequoit Bay this  
afternoon between 3:00 and 4:30 PM.  The lighting was excellent with the  
late afternoon sun.

There were probably 2,000+ gulls spread out from the southeastern corner  
near Bazil restaurant to Sutter's Marine on the western shore, resting on  
the ice and feeding in the open water.

Great Black Backed Gull:  over 150 split about evenly between full adults  
and various immature stages.   The adults were stunning in the bright  
sunshine; most appeared to be in full breeding plumage.

Glaucous Gull:  3.  There were two very white immature birds between the  
first and second cycles, with black-tipped pink bills.  One bird's black tip  
was about 25% of the length of the bill; the other's black tip was about 33%  
of the length of the bill.   The third bird was an almost-adult that looked  
to be exiting the third cycle and entering full adult-hood.  It was  
immaculately white about the head, but its bill did not have a red gonys  
spot; instead there was just a slight hint of a black ring around the bill  
about one-quarter of the way from the tip. 

Thayer's Gull: 1.  This bird was a full adult, in breeding plumage.  It was  
noticeably smaller than the Herring gulls standing near it; about midway in  
size between the Ring Billed and Herring gulls.  It had an immaculate white  
head - no streaking at all.  Its overall aura was of a much daintier bird  
than the Herrings.  Its legs were very pink in the bright sunshine.  Its  
yellow bill had a very small red gonys spot; much smaller than the spots on  
the Herring gulls' bills, and almost hard to discern if the bird did not  
have its head at the right angle to my view through the scope.

We (Wild Birds Unlimited owners) have been made aware of Salmonella in 
Siskins and Redpolls since early Jan.
Below are many articles on the subject. This is long, but worth reading 
to the end.

Here is what was said by a new Wild Birds Unlimited store owner. Please 
note his credentials under his name:

"I wanted to share some information about sick or dying Pine Siskins. I 
am new to this list as I, along with my wife Barbara and a good friend, 
Becky Uhler, are in the process of opening our new Wild Birds Unlimited 
store here in Eugene, Oregon. I have taught Ornithology in the biology 
Department of the University of Oregon for over 30 years and I also 
often respond to questions asked on a listserv of birders in Oregon 
(OBOL, Oregon Birders OnLine). Questions concerning sick Pine Siskins 
come up every couple of years. Here is my response to one person who 
felt like she must be doing something wrong and wondered if she should 
stop feeding for awhile. ---

The usual cause of sick and dying Pine Siskins is Salmonella bacteria. 
There are two primary species of the Salmonella bacteria that often 
infect birds, but these are subdivided into over 2,300 variants and to 
make matters more confusing, some of these variants are sometimes 
referred to as if they were a separate species. Thus, Salmonella 
enterica typhimurium (a common type of fowl typhoid) is often simply 
called S. typhimurium. This can be confusing when trying to find 
information online about Salmonella.

One of the two species (S. pulorum) most often infects waterfowl and 
grouse, and most frequently, domestic fowl. The other species (S. 
enterica and its many strains) is what infects many wild birds (and 
people). Different species of birds can react differently to infections 
of Salmonella. One study on Herring Gulls showed they passed out the 
bacteria in their feces, but showed no physical symptoms at all. Some 
kinds of birds show mild lethargy for a day or so, but little else. On 
the other end of the spectrum are Pine Siskins who seem to be more 
susceptible than any other species. I don't know the physiological 
reasons for such differences, (or if they are even known) but it seems 
to be the case that Pine Siskins have a much higher mortality rate from 
this disease.

A friend of mine who has an international reputation among wildlife 
rehabilitators and has over 30 years of experience, tells me that she 
has never successfully been able to save a Pine Siskin that has been 
infected with Salmonella. They always die before any treatment has time 
to work. It is distressing to see them come to feeders being sick and 
dying. We have had many sick siskins at our feeders this year as well. 
These kinds of outbreaks of Salmonella are more common in the west than 
in the east, but I don't know why, as conditions are not that different.

Salmonella as a disease in birds, is relatively rare in the wild, but 
outbreaks do occur from time to time and then we often see the evidence 
at our feeders. Many birds with mild infections can carry the disease 
without showing any symptoms and simply pass it out in their feces. But 
the bacteria is still active. When a susceptible individual of an 
easily-infected species, like Pine Siskin, picks up the bacteria, it 
proliferates quickly in the infected bird's gut and is passed along to 
others via the feces.

Salmonella is most easily passed between individuals by contact with the 
feces from infected birds and Pine Siskins are especially social, 
allowing such easy transmission of this disease. Feeding in close 
association with one another makes it a certainty that the disease will 
be passed to other individuals from an infected one. Keeping feeders 
clean is essential at such times, but unfortunately, that alone will not 
prevent the spread of this disease. It is recommended that feeders be 
cleaned with a 10% bleach solution (followed by careful rinsing then 
complete drying before reuse) and/or that feeding be stopped for a 
period of time (2 weeks?) to let the birds move on and not get 
reinfected. However, the bacteria can survive for many months on 
uncleaned feeders, on the ground, on plant or other surfaces. It can be 
passed by other birds less susceptible to the disease, by reptiles, 
mammals or even some invertebrates. Preventing it is almost impossible. 
Once brought to a communal feeding area (which can be a wild feeding 
area or a feeding station), the disease quickly spreads. Even if you are 
very efficient about keeping your feeders and feeding area clean, 
Salmonella may be brought in from surrounding wild areas.

Salmonella is less frequent, but still very common in Evening Grosbeak, 
House Sparrow, Brown-headed Cowbird, Northern Cardinal, and Goldfinches 
(especially American). It occasionally occurs in House, Purple, and 
Cassin's Finch and is infrequent to rare in most other species of songbirds.

Because siskins are the most susceptible, and because they are so tame 
and can be numerous at feeders, we see it in them most often. However, 
be assured that there is nothing wrong with what you are doing and that 
this disease is just as frequent in wild areas as it is at feeders. We 
just see it more easily at feeders because of their high visibility.

There is also no difference between using shelled or unshelled seed! The 
seed you supply is NOT the source of this infection. The bacteria is 
spread via the feces of infected birds which which can get on either 
type of seed with equal ease. Pine Siskins can be messy eaters and spill 
many seeds on the ground. I have used both shelled and unshelled black 
oil sunflower and the mess below the feeder when Pine Siskins arrive is 
about the same. With many birds feeding at the same time, it is 
inevitable that some seed will be contaminated by feces. This happens in 
wild areas just as frequently as at your feeders.

If you handle a sick or dead bird, or feeders where lethargic siskins 
have been attending, be sure to wash your hands very thoroughly. This 
form of Salmonella can be transmitted to humans and is the most common 
type of "food poisoning." It will cause extreme diarrhea and very, very 
intense intestinal pain. Death has been known, but is uncommon; however 
dehydration is typical and may be what ultimately kills the Pine 
Siskins. Having experienced Salmonella poisoning personally (from an 
unknown source), I can assure you that you do not want this. It is the 
single most painful experience that I have ever had.

Keep your feeders clean and intensify doing so when many siskins are 
frequent, but be assured that you are doing nothing to cause this 
naturally occurring and cyclic problem."

Salmonellosis:
http://www.birds.cornell.edu/schoolyard/all_about_birds/feeding_birds/bird_di 
seases.html

Salmonellosis is caused by a bacteria belonging to the genus Salmonella. 
It is a common
cause of mortality in feeder birds, but the symptoms are not always 
obvious. Sick birds
may appear thin, fluffed up, and depressed and may have pasted vents and 
swollen
eyelids. They are often lethargic and easy to approach. Some infected 
birds may show no
outward signs, but are carriers of the disease and can spread the 
infection to other birds.
Salmonellosis is primarily transmitted by fecal contamination of food 
and water by birds,
though it can also be transmitted by ingestion of contaminated feeds or 
from bird-to-bird
contact. Occasionally, outbreaks of the disease cause significant 
mortality in certain
species.

Salmonellosis (sal-muh-nel-LOW-sis)
http://www.nwhc.usgs.gov/publications/fact_sheets/coping_with_diseases_at_bir 
dfeeders.jsp

Salmonellosis is a general term for any disease in animals and people 
caused by a group
of bacteria known by the Latin name Salmonella. Birds can die quickly if 
the Salmonella
bacteria spread throughout the body. Abscesses often form in the lining 
of the esophagus
and crop as part of the infection process. Infected birds pass bacteria 
in their fecal
droppings. Other birds get sick when they eat food contaminated by the 
droppings.
Salmonellosis is the most common bird-feeder disease.

Do bird feeders spread disease?
http://www.birds.cornell.edu/pfw/AboutBirdsandFeeding/FAQsBirdFeeding.htm#Spr 
eadDisease

This question has at times been debated in the media. Feeders, 
especially improperly
maintained feeders, can spread disease. However, there's no way to know 
if disease
transmission at feeders is any less or greater than disease transmission 
in the wild. Birds
that contract and spread diseases, such as salmonellosis, at feeders are 
typically social by
nature and would aggregate whether at feeders or not.

Public health significance
http://www.dnr.state.wi.us/org/land/wildlife/whealth/issues/salmonellosis.pdf 


Salmonellosis is of public health concern because all strains of 
Salmonella are
potentially pathogenic to humans and animals. However, it appears that 
wild birds
mainly acquire the disease from the environment and that infected wild 
birds play a
relatively small role in the transmission of disease to domestic animals 
and humans.
While dogs and cats are rarely infected, pets should be discouraged from 
consuming bird
carcasses to reduce risk of contracting salmonellosis. Any potential 
human risk can be
minimized by wearing disposable gloves when cleaning a bird feeder or 
birdbath.

Key Messages - Salmonellosis Outbreaks
? Despite what some media has implied, people who feed the birds should 
not be
blaming themselves because they see sick birds at their bird-feeding 
stations. In
fact, the disease, which is transmitted by infected fecal matter, can occur
wherever flocking species gather together -- in the woods, fields or 
barnyards.
Birds that feed in landfills, dung piles, waste water discharge areas, 
and sewage
lagoons are also at a high risk to be infected.
? While Wild Birds Unlimited has extensive experience and expertise in 
the care
and feeding of wild birds, the company is not the expert on 
salmonellosis. We
have expert resources we can use to help educate our customers with the 
facts
about salmonellosis, and our aim is to be the conduit, if needed, so 
that your
customers know how to obtain more information from these experts.
? In following the recommendation of the Washington Department of Fish and
Wildlife (WDFW), advise your customers to ?temporarily discontinue bird
feeding, or take extra steps to maintain feeders,? if they have Pine 
Siskin,
goldfinch or House Finch showing symptoms of salmonellosis. These symptoms
include droopiness, diarrhea, and severe lethargy,fluffed out feathers 
and are easy
to approach. Some birds may appear severely emaciated or be observed to 
seizure.
? Please ask customers to report any sick birds to their nearest Wild Birds
Unlimited store or local wildlife officials.

? If your customers have removed their feeders after observing infected 
finches,
you can recommend the following steps:
o Remove all feeders for a few days.
o Clean and sanitize all feeders, poles and the feeding area (See 
Responsible
Birdfeeding Handout.)
o Reinstall multiple feeders in new locations that are spread far apart 
from
one another. Reducing crowding at feeders helps reduce stress and the
transmission of the disease.
o Replace wooden feeders with ones made of plastic or recycled materials.
Wood is very difficult to sanitize.
o Do not reinstall feeders that allow contact between fecal material and 
food
(such as platform or tray feeders)
o Initially provide food and feeders that will not attract finches (suet,
safflower, peanuts, hummingbird feeders, etc.)
o Reinstall finch feeders and food after an additional two weeks.
o Clean feeders and birdbaths with a 10% bleach solution several times a
week, be sure that feeders are dry before filling them with seed.

? If customers have not observed finches with any symptoms of the 
disease, you
can recommend the following steps:
o They can continue to feed by taking a few extra steps to maintain 
feeders.
o Advise them to clean and sanitize all feeders, poles and their feeding 
area
as soon as possible.
o Have them follow the recommendations found in the Responsible
Birdfeeding Handout and or the National Wildlife Health Center
recommendations.
o They can continue to provide food and feeders that will not attract 
finches
(suet, safflower, peanuts, hummingbird feeders, etc.) even if they choose
to stop feeding finches.
o If they continue providing finch feeders and food they should sanitize 
their
feeders every few days.
o The Washington Department of Fish and Wildlife (WDFW) also
recommends that they,? reduce the number of feeders they maintain and
spread them out, use feeders that accommodate fewer birds (using tubes
rather than platforms)? and that, ?keeping bird baths and fountains 
clean is
also important.?

The Complete Story ? from the National Wildlife Health Center web site:
Birds do get sick. Disease is one of many natural processes affecting 
wild species. Sick
birds do show up at feeders, and other birds can get sick as a consequence.
Just because bird feeding is not problem-free does not mean that it is 
bad or should be
stopped. It does mean you have an ethical obligation not to jeopardize 
wild birds. What is
called for is intelligent bird feeding. (WBU calls it responsible 
birdfeeding)

http://www.nwhc.usgs.gov/publications/fact_sheets/coping_with_diseases_at_bir 
dfeeders.jsp

Wild Birds Unlimited Recommends Responsible Birdfeeding:
It is always important to provide a safe feeding environment for the 
birds and it becomes
even more critical during episodes such as a Salmonellosis outbreak. 
Responsible bird
feeding techniques play a crucial role in helping to contain the spread 
of disease among
bird populations. The following strategies will help you to improve the 
health and safety
of your birds during periods of concern about the spread of avian diseases:
? Remove all open feeder trays and platform feeders that allow fecal 
material and
food to come into contact with each other. Use only feeders that do not 
allow the
birds to stand in, or directly above their food.
? Birdfeeders with cracks and crevices are difficult to sanitize and 
should not be
used. Replace them with new feeders.
? Since wooden feeders are difficult to sanitize, they should be 
temporarily
removed during disease outbreaks or replaced with feeders made of 
plastic or
recycled materials.
? Focus on using only feeders that can be easily cleaned.
? Give the birds more space. The addition of more feeders, spread far 
apart from
one another, will reduce the crowding of birds that is often found 
around a single
feeder. This will reduce the bird?s stress and the potential for disease 
transmission
between healthy and sick birds.
? Periodically move feeders to new locations in the yard to avoid the 
build up of
waste materials and feces. Be sure to always keep the ground below and 
around
the feeders clean. Rake up and discard seed debris and bird droppings on 
regular
basis.
? Clean feeders, birdbaths and all hardware several times a week with a 
10% bleach
(one part bleach to nine parts water) solution. Rinse thoroughly and 
allow to
completely dry before refilling feeders.
? Birdseed should be stored in rodent proof containers to avoid 
contamination.
? Always discard any seed that has become wet.
? Limit the amount of seed provided to only the amount the birds will 
use in one or
two days. Clean the feeders and rake up the waste material in the area 
before
refilling.

The National Wildlife Health Center
Eight Steps to Prevent or Minimize Disease Problems at Feeders:
1. Give them space - Avoid crowding by providing ample feeder space. 
Lots of birds
using a single feeder looks wonderful, but crowding is a key factor in 
spreading
disease. If birds have to jostle each other to reach the food, they are 
crowded. This
crowding also creates stress which may make birds more vulnerable to 
disease.
2. Clean up wastes - Keep the feeder area clean of waste food and 
droppings. A
broom and shovel can accomplish a lot of good, but a vacuum such as you 
might use
in your garage or workshop will help even more.
3. Make feeders safe - Provide safe feeders without sharp points or 
edges. Even
small scratches and cuts will allow bacteria and viruses to enter 
otherwise healthy
birds.
4. Keep feeders clean - Clean and disinfect feeders regularly. Use one 
part of liquid
chlorine household bleach in nine parts of tepid water (a 10 percent 
solution) to
disinfect. Make enough solution to immerse an empty, cleaned feeder 
completely for
two to three minutes. Allow to air dry. Once or twice a month should do, 
but weekly
could help more if you notice sick birds at your feeders.
5. Use good food - Discard any food that smells musty, is wet, looks 
moldy or has
fungus growing on it. Disinfect any storage container that holds spoiled 
food and the
scoop used to fill feeders from it.
6. Prevent contamination - Keep rodents out of stored food. Mice can 
carry and
spread some bird diseases without being affected themselves.
7. Act early - Don't wait to act until you see sick or dead birds. With 
good
prevention you'll seldom find sick or dead birds at your feeders.
8. Spread the word - Encourage your neighbors who feed birds to follow 
the same
precautions. Birds normally move among feeders and can spread diseases 
as they go. The
safest birdfeeders will be those in communities where neighbors 
cooperate with equal
concern for the birds.

es_pamplet.pdf

Also John Schaust, our own naturalist at WBU:

The symptoms you describe are analogous to ones that are seen when birds 
are infected with avian salmonella which is also known as salmonellosis. 
It is primarily transmitted by fecal contamination of food and water by 
birds, though it can also be transmitted by ingestion of contaminated 
feeds or from bird-to-bird contact.

Please reassure your customers that they should not blame themselves 
because they see sick birds at their bird-feeding stations. There's no 
way to know if disease transmission at feeders is any less or greater 
than disease transmission in the wild.

Birds that contract and spread diseases, such as salmonellosis, at 
feeders are typically social by nature and would aggregate whether at 
feeders or not. In fact, salmonellosis, which is transmitted by infected 
fecal matter, can occur wherever flocking species gather together -- in 
the woods, fields or roosting locations. Unfortunately, no matter what 
the source of the disease is, sick birds will often congregate around 
feeding stations as this is the easiest source of food an infirmed bird 
can utilize.

While Wild Birds Unlimited has extensive experience and expertise in the 
care and feeding of wild birds, the company is not a veterinary expert 
on salmonellosis. However, we do have expert resources to help educate 
our customers with the facts about salmonellosis and how to responsibly 
deal with it in their own backyards.

Key information about salmonellosis is available in a packet of compiled 
expert advice which can be downloaded from the WBU Intranet and used to 
train staff and advise customers. It is available at the following link: 
http://www.wbustore.com/intranet/edu/Salmonellosis_Packet_0209.pdf

I have observed four birds with salmonellosis-like symptoms at my feeders  
this winter in Springwater township.? 
At least two died.? 
The maximum number of redpolls at these feeders was over a hundred.
The redpolls fed on the ground as much as at the feeders.? Unfortunately,  
the ground is a rough lawn and can
not be sanitized.? 
I?am discontinuing feeding.?
?
?It seems possible that feeding promotes spread of the disease by  
concentrating the birds and their feces in a small area.
>From what I've read, outbreaks of salmonellosis are common during redpoll  
irruptions.
?
By the way, the Cornell Lab of Ornithology Feeder Cam presents feeder in  
Manitouwadge, Ontario,?that daily have redpolls much whiter than the hoary  
redpoll candidates that I've seen here.
