Lunch Time

A few days ago I stopped by the local bird store to pick up some seed and Bark Butter for our birds at home. As the sales lady was leading me up to the counter with my purchases another staff member called out that the pine warbler was back for lunch. This bird comes several times a day to the door overlooking their very nice bird-feeding area, and waits until someone puts out some mealworms. It will start chipping at the door if the staff doesn't respond quickly enough. They offered me the honor of feeding it this time.
With a handful of squirmy mealworms, I slowly opened the door and extended just my arm. Almost instantly the warbler hopped over from its place on the back of a patio chair to my hand and grabbed a couple of worms and scarfed them down before returning to the chair. A few seconds later it came back for a second pass. This time I had my phone ready for the event. And it was quite the event. The bird stuck around for nearly 20 seconds eating several mealworms before flying off. It did miss the one that started climbing up my arm.
A yellow-rumped warbler came in to the chair and the sale lady said they sometimes would eat out of people's hands as well but they were a bit more shy. I think flicking the worm climbing under my cuff put the yellow-rumped off so it left. The pine warbler returned one more time for a quick bite before heading high in the trees; a pine of course.
I left the rest of the mealworms on the stone patio for the yellow-rumped friends.
It is always really amazing how small, light, and gentle wild birds are. It landed with just the slightest pressure from its feet on my finger tips. They are so light that it almost tickles like when someone is just barely running their hand over your skin.
It was an incredible experience.

Interactions at the Feeder

So I'm sitting here 30 days into the 2019 government shutdown. During these weeks, I've spent a lot of time feeding and watching the birds in the backyard. I have a log feeder that I made, it is actually the second one after the first ended up splitting after several years, fill several holes with BarkButter. It is really popular with the birds and the other day I noticed a nice waiting line forming. Several birds would sit in the nearby buckeye tree or on the edge of our deck and wait their turn. Since the feeder hangs on a 6 foot long chain from a branch in a pine tree, it moves quite a lot. Either with the winds or when a larger bird lands on it. So, unlike the the tube feeder with safflower seed where every opening is often occupied, the log feeder tends to serve a single bird at a time. Or maybe it is different kinds of birds that frequent this feeder. (Another short study?)

I was intrigued by this behavior and having nothing else to occupy my mind, I decided that I would collect a little data. Not being a field ornithologist, I just made up a protocol for my data collection. I knew I wanted an ordered list of who visited the feeder, if anyone actively displaced another bird (or tried and failed), as well as who was waiting in line. For my first attempt I decided to record everyone waiting once a minute for a 15 minute block as well as the ordered list of who visited. This morning it was quite cold for here, 21 F, so there was a lot of activity. I made a little disturbance putting some water out in the frozen birdbath. So I waited a few minutes until activity returned.

While there was pretty constant activity there, it did lack the variety that I sometimes see there. In total, six species visited the feeder during my 15 minute sampling (Northern Mockingbird, Yellow-rumped Warbler, White-throated Sparrow, Carolina Wren, Downy Woodpecker, Carolina Chickadee). Four of those were seen waiting for the feed (not the Downy Woodpecker or Carolina Wren). The vast majority of feedings happened without any overt aggression (26/28). There was also one time where a White-throated Sparrow made multiple attempts to approach the feeder but never landed or took food.

There was an average (N=15) of 0.67 birds and median of 1 bird waiting at my count times. Only once were there multiple birds waiting (both a Northern Mockingbird and a Yellow-rumped Warbler) although at that time no one was actively feeding.

The best interactions were a White-throated Sparrow that tried multiple times to dislodge the Downy Woodpecker and failed. It would fly at the feeder and then turn away. There was also an unrecorded bird that dislodged the Mockingbird once.

I'm not sure I learned a whole lot but it was a fun experience and got me thinking about data a little while I'm not working. I did figure out that that it was way harder to collect the data than I was expecting. I need either a better shorthand or collect the data less frequently. But between writing, looking at the timer for the one-minute intervals and looking at the feeder I felt was was always behind and missing something.

End of year birding

I see it has been quite a while since I blogged. A new job with more travel, a new hobby, and a couple of vacations ate into my time. I guess I also wasn't doing as much photography and somehow it seemed like blogging without pictures was a bit of a waste. But that shouldn't be the case. So here I am with the start of hopefully a few catch-up entries.
While I try not to be too competitive birding, I can't always suppress my competitive side. Especially when eBird provides you with data that is so easy to compare. As it got close to the end of the year and I had 199 species for Virginia in 2018, the 200-mark was calling. I thought maybe we would make a stop along the Eastern Shore during holiday travels to Pennsylvania, but the weather didn't cooperate. On the way up we were aiming to reach family before dark and rain arrived and the trip back was entirely in a heavy downpour. That left the last day, New Year's Eve to add that last new species. My BirdsEye app showed 8 species within 25 miles that I could add to my Virginia year list. Five had been seen at or near Fort Monroe. My wife and I bird there frequently and I consider it kind of like my local patch. We had done the Christmas Bird Count at Fort Monroe a couple of weeks earlier and had missed most of those (One showed up after that). Two hundred for the year and missed birds at "my" patch: the sirens were calling.
That afternoon we headed down with the hope of being able to see one or two of the new species along with enjoying the area. First stop was the new waterfront park in Phoebus just across Mill Creek from Ft. Monroe. A white-winged scoter had been reported a few days earlier. At the park, they recently added a parking lot and a floating boat launch. The later is now fully populated with gulls. As I scanned for the common eider that had been in the area for a few weeks, my wife set up the spotting scope. And bang, there along the far side of water was the white-winged scoter. In the scope, the while comma behind the eye was very clear. We often see the other two scoter species, black and surf, around Ft Monroe but this was the first we had seen the white-winged in the area. That was 200. But we were out to enjoy the birds so we moved on to Fort Monroe proper.
Next stop was the Chamberlain hotel where there is often a lot of ducks along the rocky seawall as well as good views of anything out by the Hampton Roads Bridge Tunnel island. Here we found some brant swimming next to the island. (I had actually seen a few while scouting for the CBC but always a pleasure to watch them.) While my wife was scanning the waters with the spotting scope, I walked to the end near the marina to see around the corner. Just over the wall was the common eider. Not 30 ft away. It was very nice looking male. While watching it we saw a Bonaparte's gull fly by. I was now at 202 for the year. Then, back around the other side of the Chamberlain we saw a female long-tailed duck swimming by. Now I was up to 203.
I was hoping to see one new species for the year to get to that round, but otherwise arbitrary, count for the year. And ended up seeing several new species and some nice views of other winter time visitors. In the end, I was a great way to end the year.
