The Spring and Fall Migration Timetable information was compiled using information from books and magazines, (see Bibliography), America Online's Birding forums, searches on the DejaNews site and many hours at the local public libraries. Alot of time and energy has been put into this Timetable and therefore, I ask that the information not be taken from this site and displayed on another site. If anyone wants this information for another web site, please provide a link to http://www.birdnature.com/timetable.html. Thank you.

How the Timetable Works:

This timetable is only for the Eastern US states of Alabama, Arkansas, Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Vermont, West Virginia and Wisconsin.

Arrival Date is an approximation date of when the migrating bird can first be seen while the Departure Date is an approximation of the latest date the bird can be seen. Some departure dates are missing on the Timetables, because the migratory bird may be a "Summer Resident" or a "Winter Resident". A good field guide will help in determining resident birds and migratory birds that are resident throughout a period of time.

Even though most cities in a given state are not listed, when birds migrate there can be a radius of up to 100 miles or more. Keep an eye on local weather conditions which can influence the arrival and departure dates of birds. Keeping a personal record and checking your dates with other bird observers around your area is a better guide.

If you find an error or would like to contribute your list of migratory dates, please send mail to birdnature@birdnature.com and I will include your name/homepage as a contributor.

Other Sites with Migration Dates:

The Mississippi Coast Bird Migration Site studies the annual timing of bird movements through three coastal counties, Hancock, Harrison and Jackson, in Mississippi. This site contains "arrival" and "departure" information of all birds which do not spend the entire year in this area.

Arrival and Departure Dates of Atlanta Area Birds lists the arrival/departure dates and abundance of each spieces.

High numbers of HPAI detections coincided with low temperatures in Thailand from October to February, when wild birds from central and northern Asia migrate into Thailand (7).

 

Therefore, seasonal conditions and bird migration might have contributed to the introduction of HPAI virus. Furthermore, the lower temperature supports survival of the virus in the environment and facilitates transmission (33).

Francisella tularensis is one of the most infective bacteria known;

Francisella tularensis is an intracellular bacterium, meaning that it is able to live as a parasite within host cells. It primarily infects macrophages, a type of white blood cell. It is thus able to evade the immune system. The course of disease involves spread of the organism to multiple organ systems, including the lungs, liver, spleen, and lymphatic system. The course of disease is similar regardless of the route of exposure. Mortality in untreated (pre-antibiotic-era) patients has been as high as 50% in the pneumoniac and typhoidal forms of the disease, which however account for <10% of cases. Overall mortality was 7% for untreated cases, and the disease responds well to antibiotics with a fatality rate of about 2%. The exact cause of death is unclear, but it is thought be a combination of multiple organ system failures.

"It could have an impact on California. We have a vibrant agriculture and poultry industry. It also can be a public health threat. It's one of the things we're testing for, but it's not in North America at this time," said Steve Edinger of the state Department of Fish and Game.

So far, about 100,000 birds have been tested in the U.S., including about 10,000 in California.

Avian flu is a concern worldwide.

Federal agencies are coordinating findings with agencies in Canada, Mexico, Russia, Japan and China.

 

Rapides Parish hunters accused of taking more than daily limit on ducks

Six hunters from Rapides Parish have been cited by Louisiana Department of Wildlife and Fisheries Enforcement Division agents for allegedly taking more than their daily limit on ducks, the department announced today in a press release. The men were cited on Nov. 11, the opening day of the 2006-07 West Zone duck season. They are accused of violating the Federal Migratory Bird Treaty Act by taking more than the daily limit of ducks on Douglas Farms in Rapides Parish. Michael Fisher Jr., 60, and Ricky L. McMickens, 45, both of Alexandria, along with Neal L. McMickens, 42, Francis Melder, 59, Joseph M. Vincent, 46, and Thomas R. Vincent, 48, all of Pineville, were cited for taking over the legal limit of ducks and failure to maintain field possession of migratory game birds, according to the Wildlife and Fisheries press release. Fisher and Melder were also cited for hunting ducks without a federal waterfowl stamp, the release said. Sgt. Travis Burnett and Senior Agent Spencer Cole checked the hunters and found them to be in possession of 11 wood ducks, three teal and one gadwall, the department reported. Further investigation by the agents revealed more wood ducks concealed where the men had been hunting and in a decoy bag hidden in the bushes near their parked ATVs, the press release reported. A total of 48 ducks were seized from the hunters, the release said. Violations of the Migratory Bird Treaty Act are punishable by fines up to $5,000, imprisonment for up to six months or both. The case will be prosecuted by the U.S. Attorney's Office. Stupid is as stupid does .

The project is being conducted by the U.S. Department of Agriculture, Guam Department of Agriculture’s Division of Aquatic and Wildlife Resources and Animal Control, the CNMI Department of Land and Natural Resources, U.S. Fish and Wildlife Service and other partners. http://www.guampdn.com/apps/pbcs.dll/article?AID=/20061206/NEWS01/61206006/1002

Chicks and wild ducks dunnit

• 09 December 2006
• From New Scientist Print Edition.

Marm Kilpatrick of the Consortium for Conservation Medicine in New York and colleagues analysed how the virus travelled by comparing H5N1 gene sequences against volumes of bird trade and migration. They found that the poultry trade explains the virus's spread in Asia but migration explains it in Europe (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.0609227103). The analysis suggests that H5N1 could invade the Americas by various routes - meaning the US should be testing different birds.

 

 

The Associated Press

BRIGHAM CITY, Utah -- A state biologist takes a fecal sample from a tundra swan and sends it to a lab. It is a small but significant step to determine if bird flu has reached Utah. There is no sign that the deadly Asian strain has hit U.S. soil, but the possibility is keeping wildlife officials in Utah on the perch. The Utah Division of Wildlife Resources said it has samples from 1,180 birds and hopes to have 120 more when the duck-hunting season ends Jan. 20. The state is taking fecal samples from ducks shot at Farmington Bay and Migratory Bird Refuge. They include tundra swans, northern pintails, northern shovelers and green-winged teal. There could be a chance that the birds nested on Alaska's northern coast and had contact with a migratory Asian bird that nested nearby in Russia. "It's a long shot for one of our birds to actually come in contact with the birds from Asia, but, hey, who knows?" said Spencer Atkinson, a state biologist. http://www.heraldextra.com/index2.php?option=com_content&task=view&id=202811&Itemid=99999999&pop=1&page=0

[The following are the private comments of Richard Thomas and do not 
necessarily represent those of Birdlife International.]


The threat posed by Highly Pathogenic H5N1 is still present and the virus 
is evading attempts to control its spread.

Today, it is generally recognised by the FAO and others that the major 
vector spreading the virus is movement of poultry and poultry products 
within the poultry industry, and not wild birds: 
<http://news.xinhuanet.com/english/2006-11/02/content_5283058.htm>

The presence of the virus [in] a national poultry industry can have massive 
financial consequences, both on the industry itself and even on national 
tourism, and it is perhaps not surprising that government cover-ups of the 
presence of H5N1 have been alleged: 
<http://www.abc.net.au/pm/content/2004/s1032638.htm>
<http://news.bbc.co.uk/1/hi/world/asia-pacific/3427249.stm>
<http://www.theage.com.au/news/world/bird-flu-coverup-alleged/2005/10/20/1129775901802.html>

Findings indicating arrival of the virus from within the poultry industry 
have been played down in favour of an alternative theory claiming arrival 
via wild birds: <http://www.the-scientist.com/news/20050715/01/>

However, the movement of H5N1 from outside its Asian core range to Eastern 
Europe, Africa, the Middle East and South Asia all tally much better with 
movement through the poultry trade than through wild bird migration.

Outbreaks from China leading west to Eastern Europe follow road and railway 
lines. No wild bird migrates in this direction, nor does any species spend 
the spring in the east of its range, but autumn in the west. The outbreaks 
broadly follow the Silk Road, a well-established trading route, and there 
are reports of long-distance H5N1 transport from a contaminated poultry 
factory in a city directly on this route: 
<http://www.fao.org/docs/eims/upload/152954/AVIbull006x.pdf>

See also moderator MHJ's comment in: ProMED-mail, Avian influenza, poultry 
vs migratory birds (02) Archive 20060218.0536 posted 18 February 2006.

Outbreaks in Egypt and India occurred within the commercial poultry 
industry (and there is at least one report that defective vaccines were 
involved): <http://weekly.ahram.org.eg/2006/794/eg7.htm>

The transfer of the virus to Nigeria was, with hindsight, entirely 
predictable, based on economic and trade considerations. Poultry imports to 
Nigeria were officially banned because of H5N1 fears, but the country 
lacked the technology to raise sufficient day-old chicks to meet its own 
demands, and commercial poultry farmers were calling for the ban to be 
lifted. 
<http://www.zartechltd.com/news/Magazine/Jan_200.../jan2005mag.asp?pageno=Page%2021&pagepix=21.jpg>

To overcome the shortage, chicks were being imported illegally, with China 
and Turkey both stated by the Nigerian Agriculture Minister as sources, 
whilst chicks were being flown from Egypt to the Niger Republic via Kano 
airport in Nigeria -- where the first case of H5N1 was reported in a 
commercial "biosecure" farm (both Egypt and the Niger Republic reported the 
virus a few days later): 
<http://www.birdlife.org/news/pr/2006/02/avian_flu_nigeria.html>

The FAO found that backyard poultry production was, at least in Thailand, 
less risky in terms of H5N1 infection than closed, "biosecure" poultry 
factories, a finding that doesn't implicate wild birds in the virus's 
spread: 
<http://www.fao.org/AG/AGAINFO/projects/en/pplpi/docarc/pb_hpaibiosecurity.html>

There was a similar finding in Laos, where 42 of 45 outbreaks were found on 
commercial enterprises: 
<http://www.fas.usda.gov/gainfiles/200503/146119131.pdf>

The recent outbreaks in South Korea follow a similar pattern (as did 
outbreaks in Nigeria, Egypt, India and Japan) with "biosecure" operations 
infected, but adjacent, "less-secure" farms unaffected:
<http://www.birdskorea.org/eyewitnessDEC06.asp>

Other potentially major virus-spreading vectors that appear to be little 
researched include the spreading of poultry manure on fields (see the 
"muck-spreading" photograph accompanying 
<http://www.fao.org/AG/AGAINFO/projects/en/pplpi/docarc/pb_hpaibiosecurity.html>, 
overflow ponds associated with poultry operations, which can lead to 
contamination of the surrounding environment: 
<http://www.uswaternews.com/archives/arcrights/3tysple7.html>, and the use 
of chicken faeces as animal feed.

All of these are plausible sources for the virus that contaminated wild 
bird populations in the Black Sea region in early 2006. Subsequent cold 
weather led to a scattering of dead H5N1-infected wild birds across several 
European countries. To date, this represents the strongest evidence that 
wild birds can fly a significant distance before dying after infection. A 
recent paper argues that wild birds are victims of biosecurity lapses 
within the poultry industry, but that once contaminated, they are unlikely 
to be able to sustain the virus for any length of time: 
<http://www.mun.ca/serg/Muzaffar06AvianFluFinal.pdf>. As expected, the 
European outbreaks ended abruptly, and there is no evidence the virus has 
persisted in wild bird populations.

As the European cases show, there is no doubt that wild birds are involved 
to some degree in the virus's spread, but this role has been massively 
overstated by some (especially the media). The key to halting the virus's 
further spread undoubtedly lies with better biosecurity measures within the 
global poultry industry.

English zoos to vaccinate birds against avian flu
Source: FWI	04 January 2007
DEFRA announced in December that zoos in England would be allowed to vaccinate birds against avian flu subject to meeting the eligibility criteria. But Scotland and Wales have decided to not vaccinate birds in their zoos as the current risk level is low. DEFRA argued that English zoos, when they have gained permission to vaccinate their birds, will be aiding global conservation. A DEFRA spokesperson said: DEFRAs position on vaccination for birds outside zoos remains unchanged.  We do not intend to permit the vaccination of birds outside zoos in advance of a disease outbreak or as an immediate disease control response.

Bird waste poses possible health risk

Droppings fall on Holliday, Broad, Kemp

By Michael Hines/Times Record News
January 10, 2007

Medical/military reporter Michael Hines can be reached at 940-720-3456 or by email at HinesM(at)TimesRecordNews.com

Pigeon droppings aren't just found beneath the city's underpasses.

While the city focuses on ousting birds that have gathered at the Broad and Holliday street overpasses, there's no reason to think the flock stops there. Medians along Kemp and Call Field also show the tell-tale signs of bird bowel movements. They may not be as big a deal, though, based on the outcry to Larry Krugle, street superintendent for the city.

"I've not had any complaints," he said. "The best thing you can do is run a street cleaner through it."

The city cleans its streets about every six weeks, a good idea in light of the health hazards posed by such waste.

Three types of illnesses came to Tom Sidwa's mind in connection with bird droppings. The manager of the zoonosis control branch of the Department of State Health Services pointed to the virus salmonella as well as fungal problems related to the build-up of the waste.

"There are certainly pathogens in feces of virtually any species," he said.

Salmonella bacteria already exist in the intestines but get out along with feces. With bird droppings, the chief problem would be falling into the mess and not washing up afterward.

"The solution to that is personal hygiene," Sidwa said.

Fungus problems arise because of birds' continual waste.

Cattle egrets are the main spur to one type of fungus.

"What's happening is that the environment that feces provides allows these organisms to develop in that matrix," Sidwa said, explaining things can get really bad when the dried waste gets into the air. "Feces from a bird has a potential of causing organisms that can harm people."

Similarly, droppings from pigeons that accumulate can result in the yeast-like fungus Cryptococcus. It can cause problems in the lungs and nervous system.

"Cryptococossis is really a big problem with AIDS patients," Sidwa said.

Another bird concern comes from fliers such as parakeets, turkeys and ducks. The infectious disease appears as mild, nonspecific flu-like symptoms.

"With the fungus, the take-home message is don't disturb it by trying to clean it out unless you know what you're doing," Sidwa said.

Overall, though, health problems from bird droppings aren't something that happens very often at the level of droppings seen in city settings.

"It takes some doing," he said.

EU animal health experts have tightened rules for the import of live
captive birds as part of the bloc's strategy to fight bird flu, the
EU's executive Commission said in a statement on Thursday. "Under the
regulation agreed today, only specific countries or regions which
have already been approved to export live commercial poultry will be
allowed to export captive birds to the EU," it said.

The list of countries approved to export live captive birds to the EU
would be limited to those already approved to export live poultry to
EU markets, it said. These were Australia, Canada, Chile, Croatia,
Israel, New Zealand and the United States, along with certain states
in Brazil. However, certain 3rd countries that were geographically
close to the European Union would be exempt from the new rules, it
added -- Andorra, Lichtenstein, Monaco, Norway, San Marino,
Switzerland and Vatican City.

"I am very glad that member states could agree to these tighter rules
for captive bird imports," EU Commissioner for Health and Consumer
Protection Markos Kyprianou said. "The devastation that the H5N1
avian influenza virus has caused globally serves as a reminder that
we can take no chances in this area," he said.

The EU's new rules will not apply to certain types of birds,
including commercial poultry and pet birds accompanying their owners,
since these were already covered by separate EU laws. Exporter
countries will have to prove the absence of bird flu as well as the
highly contagious Newcastle disease virus. Birds destined for EU
countries may not be vaccinated against avian flu and all imported
birds will have to be individually identifiable through a leg-ring or
microchip.

I am not an ornithologist. I was trained in ecology and evolution and
now work on human influenza. But I do know my local birds in Orange
County, California. So take it for what it is worth, but I swear I
had a pair of birds at my feeder during 2006 that looked exactly like
those in your link:
<http://tariquesani.net/albums/userpics/DSC_37062843_filtered.jpg>.

They were so striking. I tried to look them up in my Peterson's guide
and of course failed. I don't know if there are any other similar
looking species of Munias, but the dark rusty red face and
characteristic chest were what I was searching on.

Orange County/LA is home to millions of Asian immigrants and a
hospitable climate for immigrant birds as well. I assume they are pet escapees.

I wondered if the hard-core birders in Orange County had seen my
munias. So I went to the web site of our local Audubon society and
found this link: <http://groups.yahoo.com/group/OrangeCountyBirding>

Go there and search on "Munia". [There are 5 entries - Mod.MHJ]. It
is not too clear which or how many species of munias people are
seeing from these notes. But nobody seems surprised by seeing them.
And the posts are several years old.

My friend Tom Smith, an avian ecologist at UCLA, suspects that what I
saw were escaped "cage birds", which makes me wonder whether a call
to a pet store specializing in exotic birds might not shed a lot of
light on this issue.
