Well, the plan is to account for false negatives by studying factors
influencing detectability and then use those to model occupancy. It might take
a couple of years though before we can say that we have accounted for them.
The basic setup we’re looking to establish is 52 transects (260 points) spread
out over an area similar in size to the state of Indiana, surveyed multiple
times per season in spring/summer and winter. That alone will keep us hopping
for the first couple of years on the project. Beyond that our work here could
be quite different, e.g., focused on a smaller area for real census and
productivity analysis? We just don’t know yet.

Hi Tim,
The clarification is helpful. It reminds me that we did discuss that detecting
shrike is situational. In areas that are flat and open, and without a lot of
shrubs e.g. areas where shrike are focused around road-sides due to utility
wires, nest shrubs, etc., it can be quite easy to spot them. In other areas,
such as those in Ontario, West Virginia and some others, it is hard to do so.
So time required will vary.
Given that you don't seem to have a paucity of shrike, the question then seems
to hinge on what happens with 'false negatives' i.e. you don't find a shrike
but one is there. But I believe Dylan noted you were including efforts to
quantify detectability? In other words, seems like you've accounted for this.

Dear Working Group folks,
I’m sorry that I’ve not been able to participate in discussions on Tuesdays as
they conflict with one of my classes. I think they conflict with one of Dylan’s
too, so I appreciate him taking some time to connect with this group and for
the warm welcome he’s received.
I think a bit of clarification/perspective might be helpful regarding the work
we’re getting started in Oklahoma. First, shrikes are significantly more
widespread and abundant in this part of the world than just about anywhere east
of the Mississippi River and north of the Gulf Coastal Plain. Their
distribution within the Great Plains is somewhat enigmatic, but they’re still
“common” here. We’re hoping to learn something about land management practices
and other features that are either sustaining/working against them here to
potentially stave off yet another portion of the distribution where the
population has plummeted.
Next, we’re operating at scales from site-specific to regional, in an occupancy
and detectability approach. We’re surveying but by no means censusing. Dylan’s
“study site” is a 26-county area of central Oklahoma: we’ll not be mapping
territories, monitoring nest success, banding birds, etc. on this specific
project. We want there to be many surveys on which we find no shrikes.
^Those two things combined will make us quite an outlier compared to other
studies with a much more intensive than extensive approach. Dylan has been
tinkering and we have been advising on field methods for a quasi-random,
spatially-blocked, road-based sampling design for our vast study area. I’ve
been a Guinea pig for some of these initial trials, and I can offer the
following: I’m now 4/4 in detecting shrikes on our transects, and in all four
cases I’ve detected the bird in the first 2 minutes of the 5-minute count. If
anything, we might need to get less efficient at finding shrikes to conduct our
analysis.
We’ll definitely keep this Working Group up to speed as we hit milestones or
have more to report. May we all one day suffer from our "problem” of “too many”
shrikes,
~Tim

Dylan,
I apologize. I wasn’t able to listen to the full meeting. Can you advise the
purpose of your survey. Is it to develop a population estimate or quantify
habitat characteristics at known territories, or find new territories, etc. It
seems that limiting surveys to 5 kilometers and only searching/listening for 5
minutes per stop would not be very productive with a high probability of
missing appropriate habitats and or missing known territories depending on the
starting point. LOSH can be quite difficult to find even during 15 to 20
minutes of searching known territories.

Hi all,
As promised in the meeting today, I am sending out my data sheet to the list
serve. Please see the attached copy. I am using this data sheet for surveying
shrikes in Oklahoma during both winter and summer. My surveys entail driving
along the road and stopping at five 1-km spaced points to look/listen for
shrikes and kestrels (5 min. per point). Please feel free to reply back to me
with any feedback that I could use to modify my data sheet for increased
effectiveness and/or to adopt the data sheet for your own purposes if it would
be useful.
Thanks,

Central / 1 Eastern time
Hi folks,
Please find attached the notes from our February call - our call tomorrow will
be a follow up to these. The zoom link for tomorrow's meeting is:
https://us02web.zoom.us/j/86940553037
The invite in full is pasted below.
I've also attached what I hope is a calendar invite for those of you who use
Outlook and added this link to addresses within the meeting, which I hope will
ensure this meeting shows up in your calendars. If none of this works, let me
know and I'll try again.
I am also attaching again the Road to Recovery questionnaire to help guide our
discussion tomorrow. I'd like to focus our discussion how we can improve the
working group, achieve 'sustainability' and, if folks have ideas, discuss how
we can move ahead and try to get a paid coordinator.
If we have time, I'd also like to review where we at at for the eastern focused
species conservation plan and discuss how to move this ahead. I realize that
not all Working Group members participated in the workshop/meeting, so we'll
leave this to the end of the meeting, and folks can drop off as they desire.
For those interested, both who attended and didn't, here is some information
and links to work that Jessica and Stephanie did following the meeting, at my
request. They hope that we'll be able to take on the action planning ourselves.
Discussion will, I hope, focus on how we can get this done, as well as
timelines.
