Hybridization and conservation - how are they related?

Posted by Brian on October 5, 2019 at 3:25 PM Comments comments (2)

A recent interview with The Wildlife Society was just posted on their website (see below), check it out here: https://wildlife.org/researchers-discover-hummingbird-hybrid-zone/


As is pointed out in the interview article, I'm highly suspicious this hybrid zone, although it arose naturally, is larger than it would be in the absence of human disturbance and landscape alteration. Anthropogenic disturbance and habitat modification are reshaping species distributions and bringing...

Research updates

Posted by Brian on July 19, 2019 at 1:05 PM Comments comments (2)

Hi everybody!


It's been a while since I've updated you all on my research progress, so I thought I would do so now. 


First, my first paper, from my undergraduate research at Cal Poly Pomona, titled "Trends in bird species richness in the midst of drought", was recently published in the June 2019 edition of Western Birds! This one is based on my work as an undergraduate, and investigates the effects of drought on coastal sage scrub bird communities usi...

More progress!

The last week and a half has been really productive! To date, we've caught 40 birds in 26 days. Most species of plants seem to not be flowering yet for some reason, and although it makes it tougher on the birds (I'm sure the populations will be just fine in the long run), it makes our work a lot easier, because they storm my feeders. Out of 9 or 10 localities that I planned to sample this season, we're working on the...

Best laid plans

Posted by Brian on March 26, 2018 at 11:10 PM Comments comments (0)

It’s been an interesting couple of weeks since the field season began. Field work is nothing if not unpredictable. Broken laptop, broken recorder, snow in northern California, snow on the Oregon coast. I woke up a couple mornings ago, nearly slipping and falling in the slush at my feet, then looked around and saw that snow was falling from the sky. Unfortunately, after leaving northern California a couple weeks ago due to excessive snow, birds had not yet arrived in Florence, OR, so we ...

And so it begins

Posted by Brian on March 14, 2018 at 1:20 AM Comments comments (0)

Hi everybody! I’m doing the same thing as last year, attempting to blog my experiences in the field at least once a week to keep in touch (and show that I’m still alive). This year, the first task on the agenda is to start (and finish) the inland transect in northern California along Bigfoot Highway. Now that the coastal transect is mapped out, it will be interesting to see whether selection acts in similar ways on the system inland as it does along the coast. After that, I will p...

Back in San Diego!

Posted by Brian on May 26, 2017 at 4:15 PM Comments comments (0)

I recently just wrapped up a 75-day field season. I caught a total of 132 birds, making the last few months successful. I'll be slowly uploading pictures and videos from the trip in the coming days. Here's a breakdown of my travel by county: San Diego-Los Angeles-Santa Barbara-San Luis Obispo-Monterey-Mendocino-Humboldt-Del Norte-Curry, OR-Lane, OR-Coos, OR. That's eight counties along the California coast, and three more from southern to central Oregon.

I've Got 99 Problems but a Bird Ain't One

Posted by Brian on May 12, 2017 at 5:20 PM Comments comments (0)

I’m in the homestretch! The transect is finished-it officially runs from Arcata, CA to Florence, OR, gradually shifting smoothly from an Allen’s-like phenotype in the south to a Rufous-like phenotype in the north. Over the next couple weeks, I’ll be posting a lot of pictures and a few videos that show what it is I’m doing out here-videos of how I catch birds and the data I gather. All of them were taken over the last few months. It...

Oregon

Posted by Brian on May 5, 2017 at 2:15 AM Comments comments (0)

As of last Saturday, sampling in California has concluded for this year. I’ll be working along the southern Oregon coast for the next few weeks, I might head to central Oregon in the Florence area (where the hybrid zone ends, and pure Rufous Hummingbird populations begin), and end the field season. The weather has gotten a lot better; less rain, more sun, and highs in the high 50s, which sometimes feels like a heat wave. I saw my first bear of the s...

Wildlife!

Posted by Brian on April 20, 2017 at 11:45 PM Comments comments (0)

The last couple weeks have been characterized by a raccoon that jumped into my car, some questionable deer, and elk herds walking nearby. Last Thursday I had to wake up super early, and I left the back hatch of the car open as I went to grab my tent. I walked back to the car, and a raccoon jumped out and left a trail of tortilla chips behind. Just before I left, he reappeared, and wouldn’t run when I approached him. I had to honk the horn to scare h...

In Mendocino County now; Humboldt is up next

Posted by Brian on April 6, 2017 at 10:15 PM Comments comments (0)

When it rains in southern California, it usually stops after a short while. When it rains in Mendocino, it doesn’t seem to have an end. At least there’s time for an update! I’ve traveled from San Diego, to Los Angeles, Santa Barbara, San Luis Obispo, Monterey, and now Mendocino. Next up (hopefully by the end of the weekend!) will be Humboldt County. It’s beautiful out here. Freezing, but beautiful. Tons of pine trees, dense forest,...
