Re: [cayugabirds-l] Northern Goshawk Fingerlakes National Forest, Schuyler Co.
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.
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. -Scott On Fri, Jan 16, 2015 at 2:54 PM, John Confer con...@ithaca.edu wrote: 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.

Oh I forgot to point where the pond is on the map. It is close to the yellow box “see inset A” but on the left hand side adjoining the black dotted line in the center of the map!

Re: [cayugabirds-l] Northern Goshawk Fingerlakes National Forest, Schuyler Co.
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 Josh On Thu, Jan 15, 2015 at 4:15 PM, Kevin J. McGowan k...@cornell.edu wrote: 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.

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.
