Migration
Update 4 January 2021. As 2020 came to a close, the majority of our marked birds had settled into wintering areas from the Mid-Atlantic, throughout the Southeast, and west along the Gulf Coast. We expect some periodic mid-winter movements as birds adjust to incoming weather systems, or begin to shuffle around in anticipation of spring migration. During this 'off season', our transmitters switch to a less-frequent location schedule to save battery life, and we will likely post fewer updates between now and the onset of spring, however the mapping tool below will continue to update as new data come in.
Beginning in late January, cooperators will begin deploying new transmitters on birds throughout the Southeast, and we look forward to a new cohort of marked birds to track on spring migration, which we expect will get underway sometime in mid-February.

We will archive updates for the 2020 Fall Migration below. For updates prior to September 2020, see our Migration Archives page, or, you can visit our data exploration page to visualize previous year's migration data yourself.
Update 21 December. Only one bird made a movement this week; QUE-2020-21 moved from its stopover location in Kentucky (where it's spent the last 6 weeks) and flew south to Mississippi and then Louisiana. We're still expecting some movement from birds in Rhode Island and Virginia (west of the Appalachians) as fall migration draws to a close.
Update 14 December. Migration is starting to slow down as most of our birds settle into their winter ranges. The last marked bird left Pennsylvania this week, leaving Virginia and Rhode Island as the last two states with birds that haven't migrated. Our most interesting movement this week was from bird #RI-2020-44, which became the first marked bird from Rhode Island to make it as far west as Mississippi.
Update 8 December. This week several migrants entered the south-central United States, including Mississippi, Alabama, Louisiana, and Texas. Another migrant has made it to northern Florida (near Jacksonville) by flying off the coast of South Carolina. Our altitude readings suggest that, as of midnight on December 4th, the bird was flying 183 meters (600 feet) over the surface of the Atlantic.
Update 1 December. Birds are currently initiating migration in Pennsylvania, Rhode Island, and Virginia. Our early migrants from Quebec and Vermont are beginning to localize in the southeast US, likely in areas where they'll stay for the winter. Two birds also entered Tennessee this week. The first flew southwest from Ohio, while the second flew almost straight west from North Carolina, flying through the valleys of the Blue Ridge Mountains.
Update 23 November. Migration has picked up in Pennsylvania, where about half of our marked birds have left for warmer locales. Our first migrant from Virginia this year has also checked in from South Carolina. It's still a little early for the rest of the Virginia birds to move, but we expect the remaining Pennsylvania and Vermont birds to initiate migration within the next few weeks as things start to get a bit colder.
Update 18 November. Migration initiation is continuing in the northeast, as more birds report having left Quebec, Vermont, and Pennsylvania. We're expecting a number of new transmitters to come online in Virginia and Rhode Island this week as the initiation dates for these birds gets closer. We're also seeing the first few birds start to settle into their winter ranges in the southeast.
Update 11 November. Birds continue to initiate migration in the northeast, with the last few birds starting to leave Maine and Quebec for warmer climes. A major movement on Halloween weekend brought several birds from Quebec west into Ohio, Kentucky, and Illinois. Some may head back east as migration continues, but we expect that at least a few of these birds will spend the winter in the Mississippi Flyway.
Update 8 November. We saw major migratory movements associated with the remnants of Hurricane Zeta moving through the northeast around October 30th, and some of our more recent uploads have confirmed this. We currently have migrating birds strung out throughout New England, the mid-Atlantic, and into the southeast. As is typical for woodcock migration, we see some birds arriving at what might be their eventual wintering areas while others remain on the breeding grounds. We expect that now is the time for good numbers of migrant birds in southern New England and points further south.
Update 2 November. We saw major migratory movements late last week and over the weekend, with birds moving out of Canada and the northeastern states (ME, VT) and into southern New England and the Mid-Atlantic. These mass movements were probably driven by the weather system associated with the remnants of Hurricane Zeta, which moved through the northeast late last week. We currently have migrating birds strung out from Maine to Georgia, and we expect to pick up more information on migrant birds over the next few days. Resident woodcock from southern breeding areas like PA have been staying put for the most part, but we have observed one bird that left central PA on October 24th and arrived in central GA on November 1st.
Update 26 October 2020: Early migrants are continuing to move south out of Quebec and Vermont. One of these birds (VA-2019-47) is anticipated to cross Lake Ontario shortly. Currently our furthest moving migrant (VT-2020-17) has moved south from northeastern Vermont into central Virginia.
Update 23 October 2020: The first few migrants from Vermont and Quebec are beginning sporadic movements south. One bird summering in Quebec (VA-2019-47) has stopped over on the northern shore of Lake Ontario. This is a common strategy among migratory birds; this woodcock will rest, refuel, and wait for favorable northerly winds before it attempts to cross the Great Lake.
Update 20 October 2020: We've continued to see a few sporadic southward movements, including a few birds trickling out of Canada into the US, and one bird marked in northern Vermont that has migrated to Massachusetts. Most birds remain stationary, but we expect to have more frequent movements over the coming weeks. In general it seems we may see a relatively early start to fall migration this year, but only the birds will tell us for sure over the next few weeks.
Update 15 October 2020: Fall migration has officially begun, although we don't believe woodcock have yet begun moving south in large numbers. Over the past 10 days we saw our first movements of a few GPS-marked woodcock that traveled south out of Canada into NY and PA. Most birds remain stationary, and with transmitters shifting to a frequent data collection schedule today we expect to have more frequent updates, and movements, over the coming weeks.
Update 5 October 2020: We've been working hard to deploy this fall's transmitters in Vermont, Maine, Virginia, West Virginia, Pennsylvania, Rhode Island, Quebec, Nova Scotia, and New Brunswick. As these new transmitters come online, their locations will be uploaded to the map below with frequent updates of woodcock locations beginning around October 15th.
Update 19 September 2020: We're currently about halfway through deploying this fall's transmitters, with collaborators working in Vermont, Maine, Virginia, West Virginia, Pennsylvania, Rhode Island, Quebec, Nova Scotia, and New Brunswick. As these new transmitters come online, their locations will be uploaded to the map below.
