With regard to playback and mob calls, the ABA Code of Ethics limits but do=
es not ban the use of audio: Here is an excerpt from their Code of Ethics:
=93Avoid stressing birds or exposing them to danger. Be particularly cautio=
us around active nests and nesting colonies, roosts, display sites, and fee=
ding sites. Limit the use of recordings and other audio methods of attracti=
ng birds, particularly in heavily birded areas, for species that are rare i=
n the area, and for species that are threatened or endangered. Always exerc=
ise caution and restraint when photographing, recording, or otherwise appro=
aching birds.=94
Audubon is more lenient: Here is an excerpt from their website:
=93Playback is one of the most powerful tools in a birder=92s struggle to s=
ee birds in the wild. It will arouse the curiosity of any species at any ti=
me of year, but it works best on territorial species during nesting season.=
Birds that might otherwise be too shy to come into the open can be attract=
ed by the sound of a potential rival. Whether this trickery has any signifi=
cant impact on the birds is not so clear.
Fundamentally, birding disturbs birds. Everything we do has an impact on th=
em. But in some situations playback can be less disruptive than other metho=
ds of attracting birds, at times even less disruptive than sitting quietly =
and waiting for a bird to show. Proponents argue that playback reduces the =
need to physically enter and disturb a bird=92s habitat and, unlike pishing=
, targets a single species.=94
So, it is no wonder that birders may feel that it=92s okay to use mob calls=
and bird recording to attract birds.
I suggest that changing this birder behaviour requires scientific evidence =
followed by strong peer pressure. I=92d be very interested to see studies,=
and, in particular, meta-analyses on this topic. The NSBS is strongly comm=
itted to putting birds first but we need to be in a defensible position bef=
ore making recommendations.
Just my thoughts!

Education is incremental. However there birders who should know better who=
still employ pishing.

Re mobbing calls regrettably it is still a common practice among birders. =
With cell phones and birding apps its easy to produce and playback them at =

Hi Burkhard,
Many bird species have mobbing calls. You may have seen the Black-capped Ch=
ickadee doing this many times. Perhaps you thought it was curious about you=
but more likely, it was letting other birds know of your presence. One of =
the fascinating things about mobbing calls is that some species understand =
the unique mobbing calls of another species as a mobbing call and will join=
in multi-species harassment of a predator. Mobbing works, it is believed, =
not so much because the predator is frightened, but because it has been out=
ed. It has lost the advantage of a surprise attack. In the past, birders wo=
uld play recordings of mobbing calls to attract a wide variety of species, =
and with the hopes flushing out a rare bird. Birders have abandoned this pr=
actice since it causes unnecessary stress to the birds and distracts them f=
rom more important tasks such as feeding young or building up fat reserves =
for their migration.

Subject: [NatureNS] Question: Starling Behaviour
Hello fellow naturalists:
We have a pair of starlings is raising its brood in a former hairy woodpeck=
er cavity in our front yard. Today, there were some 10-12 starlings scatter=
ed in the nearby branches. A few minutes later, a big ruckus broke out, wit=
h a squirrel departing the tree at high speed pursued by some 5-6 of the st=
arlings.
My question is: Are starlings known to band together in times of trouble?
If so, they must have some means of calling for help in case of a threat.
Curious,
Burkhard
