Mid-April Update

I’ve now been at Chicken Camp for a few weeks. Ryane and Gail got the camp set up and the crew oriented, so I was stepping into a well-oiled machine when my 9-seater turbo-prop touched down in Riverton. There was a light snowfall just after I arrived, and that lead to some great photo opportunities on Chugwater. I shared my first morning on the lek with a birder/blogger/education graduate student named Christian who was visiting camp for the day. It was fun to share the grouse and our project with him, and to learn about his ambitious project to use a “big year” (seeing as many species as possible) as a way to connect with birders and learn about how they use technology and form communities. His website is worth a look: thebirdingproject.com

After Christian left, we caught a HUGE winter storm, that over two days dumped at least a couple of feet of snow. I can only remember one storm that left this much– back in 2007, we had another 2+ feet that fell just after peak breeding and left a 3 day hole in our daily observations at Monument lek.

Needless to say we were kept off the leks for a few days for a few days with this year’s storm as well. Chugwater lek is fairly accessible, so we were back there after 3 days. Cottontail took another couple of days, and required a tough effort to forge a path there.

We had another visitor, Brett Sandercock from Kansas State University, who came out to Chicken Camp for the weekend. I knew Brett from my Berkeley days when he was a post-doc and I was a wee grad student. We’ve since crossed paths as grouse-ologists– Brett has been working on Prairie Chickens in the Midwest for a number of years. It was fun getting to show him sage-grouse for the first time!

 

 

We also managed a quick afternoon trip to the Nature Conservancy area in Red Canyon.

The snow seemed to extend the peak in breeding this year, and we had a lot of females showing up in the first week or so after the big storm. From the few banded females we have, we know they were there before the snow and came back again after, suggesting they might have abandoned their first nesting attempt.

A very few females we can tell individually even with out bands. Ryane had sent me a digiscope of a white-feathered female that was seen a couple of times early in the season. It came back last week, and one day I was on the lek and able to get some shots.

Losing a nest is generally a bad thing, but our Game and Fish contact said that we shouldn’t be concern. Any females that got caught by the storm were breeding early, and have plenty of time to try a second nest. Add to that the huge benefit that the big pulse of moisture will provide to the ecosystem. It looks to be a green spring out here, which should mean lots of new growth and insects for the chicks.

 

With fewer and fewer females showing up every day, we finally have a chance to start our experiments for the year. I’ll leave the topic of those for another post.

Field season underway… without me!

In a previous field season, we dug shallow trenches to prepare for laying microphone cables at Monument Lek.

For most of the past decade, the 2nd week in March would find me fully entrenched (literally) in getting our sage-grouse research projects up and running. Not this year. I took on a winter quarter class at UC Davis, and won’t be joining the rest of the crew at Chicken Camp for another couple of weeks. I’m doing what I can to help Gail and Ryane from here, but so far I’ve missed some excitement in the form of minor vehicle and trailer calamities.

From what I’ve heard- it’s been a weirdly warm winter so far, with the area getting rain (rain!) as often as snow, and no permanent snow cover when they arrived at the field site. The males were already displaying on the leks, and attendance seems pretty good, although it’s hard to know how to interpret numbers.  Does more males relative to same date last year reflect an increase in the population, or that the season has advanced, or both? We should have a better answer for this once we see how the season plays out.

I’ve been teaching Behavioral Ecology in the WFCB department at UC Davis this quarter. I’ve never taught BE before, but the subject is definitely in my wheelhouse, and my past experience with Animal Behavior and Intro to Evolution classes have definitely given me something to work from. Hopefully the 60 students in WFC 141 have learned something this quarter! Now to write that exam!

2016 Field Ad – Now Filled

[NOTE- All positions have been filled 2/2016]

We’ve now started advertising for our 2016 sage-grouse field season. This year will be a little different from normal. Most relevant to potential applicants, this year the positions will be volunteer only (room and board, but no stipend this year). We are definitely sympathetic to the opinion that all technicians should be paid, and, if possible, paid what their work is actually worth. However, when it comes down to it, the choice to get as much research done as possible on our federal grant, continue supporting the dissertation research of at least one graduate student, and yes, providing training and mentorship to technicians, outweighed the alternative (i.e. the alternative being NOT collecting any new data, running new experiments, continuing to conduct much needed population surveys, etc…).

There is a non-zero cost for technicians to join us this year, although we believe that will generally not be too high, since we do cover room and board, and there’s just not much to spend money on during the normal field season. Thinking about what costs will pop up- any pieces of winter gear not already owned, travel to the site, vehicle insurance, cell phone bills, rent at home, etc. In terms of benefits, the position should include coverage under UC Davis workman’s comp. Additionally, technicians typically receive two certifications- a BLM cert for ATV operation and an animal use certification through Davis. The less tangible advantages: working in a really beautiful place with really fascinating birds, getting trained in new techniques, and (hopefully) earning really strong reference letters. We have (or are currently) working on manuscripts that have had technicians as co-authors (although we can’t promise this), and many of our techs have gone on to great careers in ornithology, graduate school. Two former techs even joined the Patricelli lab as graduate students!

We definitely understand that for some people this isn’t enough to tip the scales, but we do believe that Chicken Camp is still a great place to spend a couple of months!

Anyway, here’s the advertisement [note please direct applications to Ryane this year]:

VOLUNTEER FIELD ASSISTANTS (3-4) needed approximately March 7 through May 5 for investigations of the behavior and ecology of Greater Sage-Grouse near Lander, Wyoming and the scenic Wind River Range. The projects are part of a larger effort in Prof. Gail Patricelli’s lab at UC Davis to understand the environmental and social factors shaping sage-grouse display behaviors- see the following websites for more information (http://www.eve.ucdavis.edu/gpatricelli/) and (http://www.alankrakauer.org).

Assistants will use video and audio recording technology to support an NSF-funded study of courtship dynamics and display plasticity on the lek. Duties include some or all of the following: maintaining camera and acoustic monitoring equipment, observation of basic courtship behavior and lek counts, capture of adult sage-grouse, radio-telemetry, data entry, and some computer and video analysis. Assistants must be flexible in their needs and comfortable living and working in close quarters in a remote field station, and able to work in adverse field conditions (mainly MUD, WIND and COLD).  Work will be daily and primarily early in the morning, with afternoon and night work required as well.

Applicants must have a valid driver’s license, basic computer skills, and have participated in at least one field biology project in the past. Previous experience/certification with off-road driving and/or ATV’s is preferred but not required (uncertified individuals will have the opportunity to get ATV certification in-field). Individuals with previous sage-grouse capture experience especially encouraged to apply. Must be able to show proof of United States employment eligibility.

Assistants will receive food and shared housing, but need to provide their own transportation to Lander and their own personal gear.  Please send a single PDF containing a cover letter, resume, and contact info for two (2) references to: Ryane Logsdon, Department of Evolution and Ecology, University of California Davis, One Shields Avenue, 2320 Storer Hall, Davis, CA 95616, or preferably by email to rlogsdon [at] ucdavis.edu.  The positions will remain open until filled, and review of applications will begin immediately.

 

Laterality paper is out!

Science is sometimes slow- case in point our recently published paper on left-right side biases in social behaviors in the sage grouse. The idea for this paper first surfaced in 2010 at the International Ornithological Congress in Campos do Jordao in Brazil. Gail and I saw a couple of plenary talks related to visual fields and left/right biases. From that we had a year or so of data collection from our videos, then about 2 years of cycles of submitting a manuscript, waiting for reviews, revising, resubmitting, etc etc etc. Feels great to finally have this out!

Thanks again to Emily, Michelle, Jennifer and Tawny who were undergraduates who helped figure out how to sample and measure the side biases, and Melissa (former Masters student) who spearheaded our collection of agonistic behaviors.

Abstract:

Lateral biases in behaviours are common across animals. Greater laterality may be beneficial if it allows for more efficient neural processing, yet few studies have considered the possible importance of indi- vidual variation in lateral biases in wild animals, particularly for social behaviours. We examined lateral biases in lekking greater sage-grouse, Centrocercus urophasianus, a species in which males show lateral orientations during aggressive encounters and courtship interactions. For aggression, we found no sig- nificant lateral bias in fights, but when examining another agonistic behaviour, the side-to-side facing- past encounter, we found a left-eye bias but only in males that successfully mated with females. For courtship behaviour, we found that successfully mating males were more strongly lateralized than nonmating males, but the direction of laterality depended on whether males were using their binocular frontal field (left-eye bias) or monocular lateral hemifield (right-eye bias). Bias depended on social context as well; nonmating males showed a bias in courtship orientation only when far from the female. Our results reveal a complex pattern of laterality depending on the mating success of the male, his behaviour and the social environment in which he is acting. We found support for the hypothesis that greater laterality may be beneficial, although the mechanism for this relationship in this species remains unknown.

International Grouse Symposium: Conference

Aurora Borealis seen from apartment

After the workshop was complete, it was time for the main event- the 13 International Grouse Symposium! This conference brings together grouse specialists from all over the globe once ever three years. It’s an interesting interval, for example the Behavioral Ecology meetings are held every other year, while the International Ornithological Congress is every 4th. I suppose three years is a compromise between keeping momentum and maintaining contacts versus making sure there are new stories to tell. IGS had around 150 attendees, mostly from Europe and North America although a few from Asia as well. The next one is planned for Utah in 2018.

The topics on display at the IGS were pretty wide ranging. My talk was pretty far on the basic science/non-applied side (it was on reproductive skew on the leks), but people definitely seemed interested. As we learned from Ilse Storch, head of the red list committee for grouse at IUCN, almost every grouse species is in trouble, and things haven’t gotten better in the past decade. That means most of the talks were management and conservation oriented. There were a lot of really sophisticated spatial analyses dealing with how birds are dealing with changing landscapes. On the other end of the spectrum, there were some presentations on husbandry in some of the most threatened grouse populations. Greater Sage-grouse were probably the most talked about species, and I think more than half of the conference focused on one of the prairie grouse species. Some of the Europeans were heard lamenting “Wow- you guys sure do have a lot of money for research!”.

With such a small meeting spread over three days, there was only one talk at a time. This is in contrast to some of the bigger meetings where you are always missing something because invariably multiple interesting talks are lined up against each other, or the concurrent sessions occur far enough apart it’s not easy to jump between rooms. It was nice to be able to catch everything, and to get to hear some really interesting presentations that I might not normally have gone to.

For what it’s worth, a discussion with Tomas Willebrand convinced me to pick up my twitter and I did a little bit of live-tweeting of some of the talks.  I’m a relatively new Twitter convert, so this was the first meeting I had a chance to do that. It was pretty fun to think of short summaries of the presentations, although I don’t think I was as rigorous as some biotweeps who seem to come up with multiple entries for each and every talk.

The venue was at the Hilton near downtown Reykjavik. One highlight of the conference was an elegant banquet on an island just north of the city, in what was supposedly one of the oldest wooden structures on Iceland.

Another highlight was getting to chat with Jacob Höglund, one of the authors of THE book on leks. Very cool to geek out about the differences between Black Grouse and Sage-grouse with one of the giants of behavioral ecology and someone who’s been studying grouse behavior (among other things) for many years.
