NEW DATA FORMS
This year the BBS embraces the 21st Century by converting to a new
relational database system using scannable field sheets and electronic
data entry. The database system consists of a Windows NT Server housed
in a Pentium PC while the management program is SQL Server. Though
the database set-up may be of some interest to those of you with a technological
bent, it should not play a significant role in how you interact with our
office. Let it suffice to say that the new system will allow much
more flexibility in how we access, manipulate, and retrieve data.
The second and more relevant change, at least from a BBS observer's perspective, is the new data sheets. They are actually very similar to the old forms but we streamlined both the data collection and entry processes, and by modifying the Field Sheets we have eliminated the need for a species Summary Sheet. Each Field Sheet still contains 10 stops, but we have used both sides of the page, 5 stops per side, to allow more room for recording data. In addition, the species listed on each Field Sheet have been tailored to the specific route based on the previous years’ data. No longer will you have to search through a huge list of species to find the ones commonly detected on your route. Moreover, the data will be electronically extracted from the data sheets using a scanner, instead of being manually keypunched, which should reduce errors, increase efficiency, and save money. Also, for the first time in BBS history, individual stop data will be available in an electronic format, not just 10-stop page totals.
With the new data sheets there is no need to calculate page totals or go through the tedium of counting stops. Our computer will do all summary calculations for you, which should reduce transcription and mathematical errors. However, to reap these benefits the data must be recorded as Arabic numerals (i.e., 1,2,3,...) directly on the new Field Sheets. If you feel that you must use hash marks, dots or other methods to count individuals, use the old field sheets (10 stops/page) which we have provided and then transfer the data to the new Field Sheets. Alternatively, you could make a photocopy of the new Field Sheets for use in the field and then transfer the data to the original. In either of the above two cases, please return both sets of data sheets to our office. But remember, if you are able to accurately count and record data in the field as Arabic numerals directly to the new Field Sheets, there is no need to transcribe data.
We are also investigating other methods of data submission, and envision implementing an electronic data submission system via the Internet or facsimile machines in the near future; updates on our progress, as well as, instructions will be posted on the Internet at: http://www.im.nbs.gov/bbs/bbs.html.
Undoubtedly, there will be unforeseen problems and delays for which we apologize in advance, but we do appreciate your patience and understanding as we all become accustomed to the new system.
U.S. GEOLOGICAL SURVEY
Since our last bulletin, the BBS has become part of a new bureau within
the U.S. Geological Survey, the Biological Resources Division, whose motto
-- Good Science, Well Managed -- reflects its mission to conduct sound
scientific research for the proper management and conservation of our biological
resources. Under this new relationship, both physical and biological
scientists will be working in close conjunction to address the pressing
environmental concerns facing our nation’s natural resources. More
specifically, the Patuxent Wildlife Research Center is now both our physical
and administrative home. The BBS looks forward to this new partnership
and to our continued role in monitoring the status and trends of the continent’s
bird populations.
1996 COVERAGE
Our thanks to all participants for another solid year for the BBS with
2913 completed surveys. Somewhat unexpectedly though, this year’s
total represents a 5.0% decrease in route coverage as compared to last
year’s record-breaking total. In the U.S., the number of completed
routes fell 3.2% to 2510, while Canadian coverage dropped 8.6% to 403.
Moreover, almost two-thirds (40 out of 61) of the states/provinces suffered
declines in route coverage.
Given the widespread nature of these declines no single cause seems immediately attributable. However, a cool, wet spring throughout much of the continent, and miles of election-year road work may have been contributing factors. This lower total also reflects the cessation of the 3-year Mexican BBS pilot project. Even accounting for the loss of those 30 or so routes, the 1996 total still falls short of last year’s total. Fortunately, the total will undoubtedly rise as misplaced and forgotten data trickle into our office over the next few months.
On a more positive note, the efforts of state coordinators Robert Reid,
Jr. in Alabama, David Watts in Mississippi, and Steve Hedges in Utah are
to be congratulated; they increased coverage of existing routes in
their respective states by almost 20% over last year. In addition,
Robert and Steve have added more routes to Alabama and Utah,
respectively, and look forward to even better coverage this summer.
With the additional routes, Alabama has joined the ranks of those states
with six or more routes per degree block, making it the first state south
of the 36th parallel to achieve this goal; other states with more
than six routes per degree block include: Connecticut (7), Delaware (6),
Maine (6), Maryland (14), Massachusetts (6), New Hampshire (6), New Jersey
(7), New York (7), Pennsylvania (7), Vermont (6), and West Virginia (7).
Although route density is determined by the availability of qualified
observers, we strongly encourage other state coordinators, especially in
the mid-west and west, to consider adding additional routes. By the
year 2000, we would like to increase the route density in the U.S. by 300
routes.

MOST ABUNDANT SPECIES
This year the most populous species along BBS routes in the U.S. was
the Red-winged Blackbird with 130,032 individuals recorded. Though
the Red-winged Blackbird was the most abundant species, Mourning Doves
were detected along the most routes (2202 routes). In Canada, the
American Robin was detected in the highest numbers (16,529 individuals)
and along the most routes (392 routes).
STATE COORDINATORS
The BBS welcomes five new state coordinators to the program this season!
You folks in California, Georgia, Kansas, South Dakota, and Vermont pay
particular attention here. In northern California, Kevin Hunting
is the acting coordinator while Lyann Comrack is away. Joe Greenberg
relinquished his role as the Georgia coordinator, and has been replaced
by Todd Schneider. In Kansas, John Zimmerman has passed the role
of coordinator to Bill Busby. After thirty years as the South Dakota
coordinator, Nathaniel Whitney has also decided to pass the torch on to
Richard Peterson. In Vermont, Steve Faccio replaces Chris Rimmer
who relinquished the coordinator role in late 1996. We extend our
heartfelt thanks to Joe, John, Nathaniel, and Chris for their years of
dedicated service and we wish them the best as they move on to new endeavors.
Other changes include a new phone number (405/332-8843) for Bill Carter, the Oklahoma coordinator, and an address change for Harry LeGrand, the North Carolina coordinator.

EXOTIC SPECIES REPORT
As discussed in Stevenson and Anderson’s The Birdlife of Florida, the
Eurasian-Collared Dove was brought to Nassau, Bahamas in the early 1970s,
where it escaped from captivity in 1974 and quickly spread throughout most
of the Bahamian islands. From there, the doves are believed to have
immigrated to Florida in the late ’70s or early ’80s. The first BBS
record for the species was on the Plantation Key route in 1986 by Alex
Sprunt, IV. The map
on the facing page depicts the distribution and population expansion of
the Eurasian-Collared Dove as detected on BBS routes. Now this species
can be found throughout Florida and in much of Alabama and Georgia, although
there have been sightings as far north as Cape Hatteras, North Carolina.
In addition, an individual of this species, thought to be a local escapee,
was detected on a BBS route in Texas. Given this species wide habitat tolerance
and history of range expansion, here and in Europe, it seems likely that
the Eurasian-collared Dove will continue to spread, establishing itself
throughout the mid-Atlantic and mid-western states, in future decades.
The Eurasian-Collared Dove is similar in appearance to the Ringed Turtle-Dove, with which it may be confused, but is usually larger and darker with gray undertail coverts. However, familiarity with its "undove-like vocalizations" (e.g., kuk- kooooo-kook, kuk k’rooo, and a catbird-like mew) should limit mis-identifications in the field.
BBS IN PUERTO RICO
As a consequence of expanding human populations and increased tourism
in recent decades, many Caribbean Islands have suffered severe environmental
degradation and in some cases irrevocable losses of biological diversity.
Although economic development should not necessarily be discouraged, it
must be balanced with environmental policies that are based on sound scientific
data. Puerto Rico, as well as most Caribbean Islands, harbor many
endemic and native avian species whose populations are not currently being
monitored on an island-wide scale. This year, with the support
of the Department of Environmental and Natural Resources, 29 BBS routes
have been established on the island of Puerto Rico, a U.S. Commonwealth,
to provide much needed information on this island’s unique avifauna.
Marking our first foray into the Caribbean, the PRBBS will be somewhat exploratory in nature as we adapt current BBS methodologies to the island setting; but we anticipate the PRBBS being as successful as its continental counterpart.

BBS PATCHES
In 1994, we distributed official BBS patches as a token of our appreciation
to BBS participants. We still have several hundred left, so if you
did not receive one then or have joined us recently, please let us know
and we will send you one. The patches will be distributed on a first
come, first served basis while the supply lasts.
STORIES FROM THE FIELD
As in past years, vehicle problems, inclement weather, poor roads,
and animal encounters have delayed and in some cases prevented observers
from conducting their surveys. But time and again, BBS participants
have demonstrated the three key ingredients of successful field biology:
preparation, determination, and observations. But even the most prepared
observers are caught unawares at times by the vagaries of nature, as was
the case for Dolores and Don Harrington. Having discovered no problems
during the scouting of the Ramsey, AR route, they attempted to run the
survey a few days later. However, a tornado had crossed the route
in the intervening days downing two large trees just after stop 28.
Unable to proceed farther, they back-tracked and detoured until they were
able to reach stop 29. Unfortunately, the delay had allowed a rainstorm
to catch them ending the survey, and losing two new species records for
the route. Undaunted they completed the route on a subsequent attempt.
Robert Daly gets the award for the most dedicated observer this year. While attempting to cross a wide water-filled pothole on the Hillsboro, AL route, he found that its normal 12-inch depth was now 3 feet and almost became hopelessly mired. He finally pulled free using the mechanical winch cable but found that his truck would not restart. Water had damaged the computer engine controls that cost nearly $1000 to repair. Incredibly, he completed the route a few days later avoiding the pothole.
The next stories illustrate how non-avian animals often enhance, for better or worse, the BBS experience. For example, at the start of the Dunckley Pass, CO route, David Pantle and his son, Hardin, narrowly avoided a car fire when gasoline fumes alerted them to holes in their gas line from which fuel was spraying out dangerously close to the hot exhaust system. While they had slept under the stars, some critters had decided to fuel-up by munching on their car’s rubber gas line. Although they suspect chipmunks or ground squirrels, the culprit was never positively identified since after the hose was repaired they had the foresight to move their camp.
While running the Brite, TX route, Ben Archer found he had no need for the strong coffee he carries. Arriving at a stop mid-way through the route, Ben noticed an apparently dead rattlesnake lying a few meters ahead in the middle of the road. Conscientiously completing the stop before investigating the carcass, he turned not only to find that the snake was not dead but that it was no longer in sight! Luckily it hadn’t decided to seek shade under his car. If this wasn't enough to keep his adrenaline flowing, a few stops later Ben found himself in the middle of a huge swarm of bees. As he stood still allowing the swarm to pass, he wondered whether they were domestic or African? It is probably better that he never found out.
Farther north, Susan Weller got quite a start while driving to the Coeur d’Alene, ID route when an atypically large white-tailed deer plowed into the side of her car -- talk about things "that go bump in the night." Fortunately, besides some frayed nerves and perhaps bruised shoulder muscles, neither Susan nor the deer were hurt. But where the buck stopped, it required $471 to repair.
Animals caused other unexpected delays as well. On the Manawa, WI route, Daryl Tessen, the state coordinator, was out of his car counting birds at a stop when a skunk decided to investigate him. After a few tentative attempts, he was able to discourage the skunk’s interest, luckily, without incident. For those of you wondering how one discourages a skunk -- Daryl writes, "Very carefully."
Other more pleasant wildlife encounters include those of Mike Hall. He was treated to a regular avian parade along the Cedar Falls, WA route when he spied a crow chasing a bald eagle chasing an osprey carrying a fish. The fish won this time though, since the osprey, perhaps intimidated by its entourage, dropped the fish while flying over a lake. Mike also enjoyed the sights of a young cougar and black bear along the route.
Ralph Keel and David Hughes also saw two black bears and a bobcat while surveying the Dismal Swamp, NC route.
The final story comes from Madelon Schouten of British Columbia. Madelon has identified the BBS Syndrome. Symptoms include tendonitis of the right elbow due to repeated gear shifting while conducting her 6 BBS routes. Unlike Tunnel-Carpal Syndrome, BBSS appears to clear up quickly with the application of cold packs and aspirin.
BETTER LATE THAN NEVER
Do you have BBS data from previous years that was never sent in?
Remember, it is never too late. Whether it is 1 or 25 years old,
we can still use it. While we don’t wish to promote late data submission,
don’t throw it out just because it’s a year or two old.
