That's an amazing shot you got. I know how exciting it can be to score
amazing shots!! :-)
The subject of to call or not to call is a good one too.
Especially as nesting season nears. Raptors in particular tend to nest
earlier than other birds.
Your Hawk doesn't look like an adult, so probably no worry there, but
calling a bird could call it away from nest and eggs.
So it's good you put the subject out there. Just something we should all
think about around this time of year.

song ID. E.g. if I'm not sure that a song I just heard is a Savannah
Sparrow or not, I'll play the song on my phone so I can check, but I don't
use speakers, play it more than once or twice, and I don't try to call the
bird in. If I know what the song is I don't play it at all.
While it seems likely that 90+% "taping" attempts have no negative effects
on the bird whatsoever, that 's not nearly good enough. 1% risk, even 0.1%
is too much for me to sanction for no good reason. Some small percentage of
tapings do have negative effects on a bird, and it's not always easy to
tell which ones will advance. For example, an NYC Audubon trip once
attempted to call in a Great Horned Owl immediately after calling in a
Screech Owl. Great Horned Owls eat Screech Owls. I've also seen a Kestrel
go after a Pygmy Owl that was disturbed by a trip leader so the group could
I would prefer taping to be strictly limited to scientific and conservation
purposes: e.g. bird counts, environmental impact surveys, and breeding bird
surveys. Recreational birding and photography should not take the risk of
using audio recordings to call in birds. I don't tape birds when I'm in the
field by myself, and I don't allow taping on trips I lead.
