But, anyway, I think this bird is on the brink, and will go extinct sooner or later.

Not necessarily. The crucial point is breeding habitat - if it really was a bomboo canebrake specialist, multiple areas must be preserved because the bamboo stands will flower and then die every few years, and until they have regrown, the birds won't be able to use this piece of habitat.

And even if the birds were more general in habitat preference, all available reports indicate that they needed habitat for breeding that was subject to irregular, not too heavy flooding - i.e., that took some time to reform after a particularly heavy flood. Thus, there was probably no patch of habitat that was populated every year. This means that the area to protect would be quite large, to preserve a variety of places for the birds to choose the best breeding sites.

I agree with dysmorodrepanis, we havent been able to locate any breeding or wintering localities in recent years. Birds has been sigthed long after the last known breeding record (in 1937) which suggest that a small population may survive somewhere, the lack of records in more recent years suggest that the population probably is very small, altough dont have to be so small that it cant be saved, its crutical that we identify breeding and wintering localities and protect these places.

Well, here is an interesting thread about the same topic. Many people assume that it was nothing more than a Yellow Warbler.

Video of a mystery warbler taken in Cuba in January, 2002 is now available
for viewing and comments at:
www.birds.cornell.edu/bachman/mysterywarbler.html. The photographer,
Manfred Sievert, identified this bird as a possible female BACHMAN's
WARBLER. Folks who have viewed the video at Cornell Lab of Ornithology do
not believe the bird can be definitively identified, but we wanted to make
the video clips more widely available for additional comments.

Feel free to pass on this URL. We would welcome the input.

Would it be possible to post the field notes taken on this bird? The
resolution is not good enough to see a few features, and it would be useful to
read
the data taken on the bird's plumage, bare parts, structure etc. that were
recorded during the observation.

I don't have a definitive identification and may not be able to offer
one. Nevertheless, I would like to suggest a way of thinking about
this problem that I think will lead to a productive discussion.
Because the observer suggested the bird might be a Bachman's Warbler,
let's try to find features that reject that identification. One of
the lessons for me from the debate about the Ivory-billed Woodpecker
evidence was that most people sought (and still seek) features that
support the identification. That's a natural inclination, but it can
lead to erroneous conclusions. This isn't to say that we should
ignore supportive characters, no. Those are necessary. The problem is
that they are not sufficient to establish a conclusion with
certainty, something we hope to do when it's important. So, I suggest
digging in and asking why it isn't a Bachman's Warbler.

I can't offer anything right up front that might help eliminate
Bachman's Warbler, but I can offer a complimentary line of thinking
that also should be followed: how can we eliminate a Golden Warbler
(petechia subspecies group of Yellow Warbler, the race on Cuba being
D. a. gundlachi)? Lurking in mangroves on Cuba, being mostly yellow
and green, and (apparently) being shaped and behaving like a Yellow
Warbler makes that the most likely possibility in my opinion. I don't
know that taxon well in life and have only studied a few in collections.

I did note, in response to Ned Brinkley's message, that the website
says: "Unfortunately, no additional field notes are available from
the photographer..." That's too bad, and illustrates the need for
practicing careful note-taking rather than relying on cameras and
recorders. Writing descriptions and taking notes is the foundation
for any observation and is what is necessary to strengthen one's
sight records. This also forces one to reconfirm, in the field, what
one thinks they saw. Such reconfirmation is what makes a sight record
more valuable as a contribution to the historical record.

One last comment, having spent too much time playing with video
analysis of blurry birds, I want to point out that deinterlacing and
recompiling video frames into a new movie makes for smoother looking
video, but it also makes alternative analyses of the original data
impossible or very difficult. Converting from the European Hi-8
format to something viewable in digital format, however, was still
essential I suppose. I should also say that I had seen parts of this
footage at Cornell in June 2005 and thought then, others did, that
the bird might be a Golden Warbler. Try to disabuse me of that bias.

Bachman’s Warbler—a frustrating, exhilarating, and continuously pursued North American bird—has been the subject of cartoons, threatened litigation, and international cooperation, but of no detailed field study. Nearly, or perhaps already, extinct, this species has been written off before, only to reappear. Despite intense collection, a continuing curiosity in and search for the species by ornithologists and birdwatchers, and a keen interest in its conservation from the time of its initial discovery in 1832 to the present day, few hard data exist to describe this elusive species. Mystery and confusion about the bird consequently abound, even relating to the pronunciation of its name. The bird was named after Audubon’s friend John Bachman, a Lutheran minister from Charleston, South Carolina, who pronounced his name “BACKman” (Buhrman 1977).

Today Bachman’s Warbler is almost a holy grail to many ornithologists and birdwatchers. The most recent specimen was collected in 1949 in Mississippi (Sciple 1950), and the last probable breeding pair was seen in South Carolina that same year (Sprunt and Chamberlain 1970). The last confirmed sightings were all near Charleston, South Carolina in 1958-1961 (Sprunt and Chamberlain 1970); see above photograph of singing male, taken May 15, 1958 by J. H. Dick. Scattered sightings in the Southeast and Cuba extend into the 1980s; see Hamel (1986) for discussions of these reports.

This early migrating, shrub or tree foliage-gleaning insectivore nests in shrubs in bottomland hardwood forests with a dense shrub layer, probably in the vicinity of openings or internal edges. Putative association with canebrakes and winter restriction to a single Caribbean island, Cuba, expose the species to habitat destruction directly through land clearing and indirectly through hurricanes and increased predation and parasitism accompanying fragmentation of forests. As will be obvious in the following account, a great deal is unknown about the biology of Bachman’s Warbler. I hope readers will forgive the abundance of conjecture that results. Perhaps naively, I hope that a future account of this species will be a biological rather than a historical one.

The Bachman's warbler (Vermivora Bachmani) was (or is) a species of new world warbler.
It ocurred (or ocurr) in swamp bottomland hardwood forest with thick and grass undergrowth in the south of the USA.
Migratory, to Cuban's criticall simillar habitat endangered
Threatened by loss of habitat, or maybe by diseases
Without records since 1958. Non veryfied records until today

now, some personal reflextions:
the BACKman was a very common but subobserved bird of the swamps of the south, and inhabited very similar habitats like of the carolina parakeet and the ivory-billed woodpecker, also extinct and probably extinct.
Nobody is very sure about the cause of the Bachman's decline, but one thing is clear: the las (and only) photographied individual was this male, observed near Charleston, where the I'on Swamp was it last stronghold.

BUT....
a female was seen in Cuba around 2002, according to the Cornell Lab of Ornithology (www.birds.cornell.edu/bachman/mysterywarbler.html)
So... it is extinct???
add comments, this is my first post i guess and my english is very primeval ajajaja so let's start

waaaaaaaaaaa!!!!!!!11 i made a post of this!!!!!!!1 ajajajajajaj i search bachman's warbler but i didn't found this post, why??? i don't know
the Bachman's warbler remember us the fragility of the bottomland swamp forest and the ambicious and destructive desires of the powerfull lumbers, not all, but the vast majority
