 may have reduced nesting success if people visit them, and goshawk are
 known to be so affected. Discretion in individual circumstances is advised.

As a follow-up to Anne's request, I'd also love to hear about any evidence
showing that Goshawks are on territory in January, and that flushing
from low cover is a typical behavior of a Goshawk on territory and

Re: [cayugabirds-l] Northern Goshawk Fingerlakes National Forest, Schuyler Co.

2015-01-16 Thread John Confer
I'm just suggesting that an overdoes of caution for the sake of a 
species that is known to be adverse to human disturbance is worth 
considering. The evidence for goshawk nest abandonment that I know about 
is limited but real.  I doubt that at this time of year that there would 
be any impact on reproductive success, but a visit in ~April-May might 
have an impact.

40 years ago Dorothy McIlroy described to me one goshawk nest that was 
abandoned while the birds were on eggs and 30 years ago John Snelling, a 
former grad student of Tom Cade, with a strong interest in raptors, also 
described such an instance. John Gregoire, below, added another 
instance(s). This doesn't approach the sample size for a publication. 
There is data for golden-wings that the number fledged per nest is lower 
for renests, but that comes from pooling nearly a dozen major studies of 
GWWA reproductive success, including a half-dozen PhDs, and is 
detectable only with a sample size of on the order of 500 nests. This 
won't happen for goshawk. So what we have is anecdotal.

Since my information on goshawk is old and very personal and not 
generally known among the public,  I wanted to make the gentle 
suggestion that for birds swuch as ravens and goshawk or similar birds 
with individual pairs that can be adversely affected by human presence 
that the location of (potential) territories and/or nests is probably 
not a good thing to share. It is interesting that within a species there 
may be pairs that are acclimated to human presence and pairs that don';t 
often contact humans and may over-react' to human intrusion. This the 
consequence of visiting a nest or entering a territory is unpredictable.

Re: [cayugabirds-l] Northern Goshawk Fingerlakes National Forest, Schuyler Co.

2015-01-16 Thread Scott Haber
John C.,

I'm still trying to figure out how we know Goshawks to be adverse to
human disturbance. Anecdotal evidence is nice, as is your research on
Golden-winged Warblers, but actual cited research on Northern Goshawks
reports the following:

*Disturbances associated with research are usually of short duration,
apparently having little impact on nesting birds. Viewing nests for short
periods after young have hatched does not cause desertion. Trapping adults
during nesting for banding or attaching transmitters apparently does not
cause abandonment. The percentage of nesting pairs with radios that
successfully raised young (83%, n = 8, 1988–1989) was similar to those
without radios (82%, n = 10, 1987–1990; Austin 1993
http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib018).
Timbering
activities near nests can cause failure, especially during incubation
(Anonymous 1989
http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib013,
Boal
and Mannan 1994
http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib034).
Logging activities, such as loading and skidding, within 50–100 m of nest
can cause abandonment, even with 20-d-old nestlings present (JRS). However,
see Zirrer (1947
http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib242)
for descriptions of repeated renesting attempts despite extreme
disturbance.*

My takeaway from that is that unless someone starts logging/timbering at
Foster Pond, I think Josh's goshawk will be fine, even if a few folks
decide to go take a look for it. This is not a situation comparable to
something like a roosting owl's location being posted, since there's no
evidence at all that the goshawk will even remain at this exact location
any longer than the single day on which Josh observed it. According to more
research cited in the BNA account, the earliest-ever recorded date of this
species being paired up and on territory is late February, and mid-March to
early April is much more common.

Exercising caution for the sake of leaving rare or poorly-known birds
undisturbed is one thing, but I think it's also worth not immediately
rushing to chastise and scold new contributors for their sightings, without
any legitimate evidence that their reports will have any negative impact on
said birds.

Foster Pond is in Finger Lakes National Forest.  It probably is not in the 
basin. But I have not looked at the details where the water flows!
Here is the map with Foster Pond!

Oh I forgot to point where the pond is on the map. It is close to the yellow

2015-01-15 Thread Joshua Snodgrass
Thank you both for the pointers. Had this been a nesting bird, I certainly
would have used more discretion. I hadn't considered the possibility of
disturbance to a possible future nesting site. This is the first rare bird
I've discovered and posted about. The last thing I want is for it to be
disturbed or scared off.
Good birding

  Concern for animal welfare is always worth considering. However, it
 seems climbing to nests is quite different than observing a bird.  In some
 circumstances, crows will abandon nests with chicks if someone climbs to
 the nest.



 Here is what the BNA account says:



 *Sensitivity To Disturbance At Nest And Roost Sites *

 Timbering activities near nests can cause failure, especially during
 incubation (Anonymous 1989
 http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib013,
 Boal and Mannan 1994
 http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib034).
 Logging activities, such as loading and skidding, within 50–100 m of nest
 can cause abandonment, even with 20-d-old nestlings present (JRS). However,
 see Zirrer (1947
 http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib242)
 for descriptions of repeated renesting attempts despite extreme
 disturbance. Camping near nests has also caused failures (*n* = 2; Speiser
 1992
 http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib202
 ).

 *Research Impacts *

 Disturbances associated with research are usually of short duration,
 apparently having little impact on nesting birds. Viewing nests for short
 periods after young have hatched does not cause desertion. Trapping adults
 during nesting for banding or attaching transmitters apparently does not
 cause abandonment. The percentage of nesting pairs with radios that
 successfully raised young (83%, *n* = 8, 1988–1989) was similar to those
 without radios (82%, *n* = 10, 1987–1990; Austin 1993
 http://bna.birds.cornell.edu/bna/species/298/articles/species/298/biblio/bib018
 ).

 I don’t see a pressing concern here, personally.



 Kevin

 HI Folks,


 The barn door is open or the cat is out of the bag, BUT I HAVE A
 CONCERN ABOUT DESCRIBING LOCATIONS OF N GOSHAWK WHEN THEY ACT SOMEWHAT AS
 IF THEY HAD A TERRITORY. Northern Goshawk are known among banders who climb
 to hawk nests to frequently abandon a nest, especially early in the nesting
 cycle, although not so much after the young have hatched.Individual birds
 can become accustomed to human disturbance at a low level and provide an
 exception. Other birds that rarely see humans may well abandon a nest if
 disturbed. At this time of year, they probably haven't started laying and,
 even if the bird is considering nesting nearby, at this time of the year
 the bird might just move away. However, if they did start to nest and
 someone visited the well described site a couple months from now, the bird
 might abandon eggs.

 I know there is an excitement in seeing a good bird, and it is very
 nice to share providing a very good motivation to share a siting with
 others, e.g., the Schofield Short-eared Owls, which do not seem to be at
 all disturbed by humans watching them in a car. Other species of birds may
 have reduced nesting success if people visit them, and goshawk are known to
 be so affected. Discretion in individual circumstances is advised.

 Cheers,

 John
