Red-shouldered Hawk!

Monday, September 1st, 2008

Thanks to Chris McLean (sprucebuddhas), we have a new view of the Welder bird feeding area, and of a Red-shouldered Hawk watching for breakfast.

sprucebuddhas: β€œWondering how birding was before 9:30 cdt this a.m. caught this culprit but unfortunately not the h-bird that was sitting on the branch next to him. He flew off while being photographed. Shy I guess.

It is probably one of the pair that is nested ~100m away and defied several attempts to capture to be fitted with a radio transmitter last year by one of the Welder fellows. He tried to capture with mice in a wire cage as well as a live barred owl on loan from a rehabber through Texas Tech.”

Eurasian Collared-Dove!

Saturday, August 30th, 2008

It apparently is something of a newcomer to Welder, since it isn’t listed at all in the checklist, but I’m pretty sure these shots that were taken this afternoon are of a Eurasian Collared-Dove. We have a lot of them in my neighborhood, and these shots show the distinguishing field marks (like the dark primaries) really well.

Here’s a shot by avatar99:

This one is by ss:

This one is by vanilla:

I know it’s an exotic (we don’t get to count them “officially” in the local Santa Barbara County list, even though they’re all over the place), but it’s still a new species for the birdcam, which makes me happy. πŸ™‚

Eastern Phoebe ID’d! (or not?)

Saturday, August 30th, 2008

There’s still some disagreement about what the earlier images showed (see the excellent summary of Texas birder comments posted by Rafa in the comments to the earlier item), but we now have a number of images that have achieved the standard for a consensus ID of Eastern Phoebe. Yay!

Here are a couple of shots that I think are among the best so far. Here’s one taken by loughman1 at 9:03 this morning:

Image 42818

Here’s another taken by rafa at 10:37:

Image 42894

Not the greatest shots in the world, but I think I’m leaning in the direction of the consensus ID. Congratulations on a new bird for the game!

Update: On further reflection, and considering birderbf’s comment and some more-recent shots of what looks like the same bird, I think I’m now leaning the other way: That this is actually an Eastern Wood-Peewee, rather than an Eastern Phoebe.

Couch’s (?) Kingbird!

Friday, August 29th, 2008

Shortly after the possible Eastern Phoebe photographed on the morning of 8/27, several shots were taken of what I’m pretty sure is a Kingbird. Unfortunately, I’m not sure which kingbird it is.

Here’s one of the best shots. This one was taken by idbirds:

Image 41738

In the chat there was some discussion about whether this was a Tropical or a Couch’s Kingbird. I can’t say I’m confident either way, but apparently enough users were confident enough for it to be successfully ID’d as Couch’s. In any event, it’s a great shot of a really attractive bird.

Things are definitely heating up on the birdcam. πŸ™‚

Eastern Phoebe?

Friday, August 29th, 2008

Some very interesting shots were taken early on 8/27. Here’s the one that I think shows the bird best, taken by txbird:

Image 41719

In the chat log (yay! I love the chat log!), rafa speculated about it being an Empidonax or Cantopus flycatcher (presumably an Eastern Wood Peewee in the latter case). But idbirds responded that it looked more like an Eastern Phoebe, and I think I agree. I’m not seeing the wingbars I’d expect to see otherwise.

What do you think?

Q and A

Wednesday, August 13th, 2008

Kay Loughman (user loughman1 in CONE) has been doing some really great work lately posing questions to various experts (as her post on the banded Buff-bellied Hummingbird shows). She and I recently put together a list of questions for the people running the show at CONE Welder, and we’ve now received answers that I want to share with you all. (Dr. Selma Glasscock at Welder indicated that she was going to be out of the office until the second half of August, but indicated she would be happy to forward some responses as well when she gets back.)

Dr. Glasscock (and others),

You had previously indicated it would be okay for users of the CONE Welder system to periodically forward you a list of questions and suggestions we had about the system. Attached is a summary of some of the questions users have submitted lately. Any responses you can pass our way would be great; I’ll post them on the blog I maintain.

Thanks.

WELDER

1. Do you have a checklist of Welder’s non-bird wildlife that you could forward to us? Many of us are interested in wildlife beyond birds. A complete list would help us to know more about the area. And in our lax time, we could speculate about the identities of generic frogs, snakes, etc. (loughman1)

John Rappole writes: Selma can correct me if I’m wrong, but I don’t believe that there is a checklist on non-bird wildlife.

2. Beyond the information in the Welder bird checklist regarding the abundance of different species in each seasons, do you have any information you can forward us about what bird species we can expect to start seeing migrating through, and when we might see them? (loughman1)

John Rappole writes: That is a book-length request. Over 300 species of migrants occur in the Texas Coastal Bend region, of which Welder is a part. Over 200 of them have been recorded at Welder. The best source for detailed information on the birds would be a copy of Rappole and Blacklock, 1985, “Birds of the Texas Coastal Bend”, Texas A&M University Press, College Station, Texas or Rappole and Blacklock, 1994, “Birds of Texas”, Texas A&M University Press.

3. The Welder checklist shows Mourning Dove as Common all year. In California they frequent seed feeders, so we’d expect to see them regularly in our area at Welder. But we’ve seen hardly any. Are they elsewhere at the refuge, or simply not as common as we might expect? (loughman1)

John Rappole writes: Mourning Doves are common at Welder all year, as are many other seed-eating species that are not visible regularly at the feeders. Why each of these is or is not at the feeders at any given moment is a study in itself.

4. Do you have any information you can forward us about what bird species have been banded with what colors at the refuge? It is often difficult to determine the band colors. Other than indicating “Banded” in the comments accompanying an image, is there anything else we could do to help identify banded birds? (birdbrain)

John Rappole writes: The only birds that I have banded to date are six Green Jays and a few Inca Doves. Selma and her assistant have banded others, but not in the vicinity of the feeders – and therefore very unlikely to be seen there.

5. Would it be possible for us to know specifically where at Welder the camera is located? We’d like to know more about the habitat beyond the camera’s field of view.

John Rappole writes: The camera is located about 100 meters WNW of the headquarters building, which should be readily visible on Google Earth. The habitat is live oak-mesquite chaparral with some elements of riparian forest. An ox bow lake (Encino Lake) of the Aransas River is about 400 meters north of the site, and the river itself another 500-600 meters beyond that.

6. We very much appreciate the efforts that have been made to immobilize the feeders to minimize movements in the wind. It definitely helps. Even better would be an arrangement of _three_ guy wires running down from each feeder, arranged so that the three wires are in separate planes. By having two guy wires running down from the feeder, diverging to different points on one horizontal wire, and then having a third wire running down from the feeder to a different horizontal wire off to one side, and tensioning all of the wires, you could create a rigid pyramid configuration that would keep the feeder motionless even on windy days. That would be very helpful for aiming and focusing the camera for close-up shots.

John Rappole writes: We have had many suggestions concerning how to improve the feeding site, all of which cost money and time that we do not have a lot of at presesnt. If this project gets solid funding, we will consider what measures need to be taken to best achieve the goals of the research.

WELDER and CONE

7. Would it be possible to add Black-crested Titmouse to the CONE drop-down menu? Although once a subspecies of Tufted Titmouse, Black-crested has been a separate species for some time now, and that is what we believe we are seeing at Welder at least half the time. (loughman1)

John Rappole writes: Although the small hybrid zone for these two forms begins just north of Welder (along the Mission River), and Tufted Titmouse range begins at the San Antonio River, only the Black-crested Titmouse is to be expected at Welder.

Yan Zhang (a member of the CONE team at UC Berkeley) writes: Black-crested Titmouse has been added as a new species.

8. Can the panorama picture be updated to reflect what the site looks like currently? The vegetation and feeder arrangement have changed since the site went live, and it would make navigating the camera easier if the panorama matched the field of view. (loughman1)

Yan Zhang writes: Concerning the panorama, may I request a new panorama image from your side, Dez? Thanks! [Addressed to Prof. Dezhen Song of the Dept. of Computer Science at Texas A&M University, co-developer of CONE.]

CONE

9. We would very much like it if logs of the in-game chat were accessible to users, preferably with date and time stamps. (tinyang)

Yan Zhang writes: We’ll figure out a way to log the chats and make it accessible.

[elanus again] So, there you have it: Some really great responses from some of the people connected with CONE Welder. Thanks to Kay Loughman for putting together the list of questions, and thanks to Dr. Rappole and Yan Zhang for their great answers (and pre-emptive thanks to Dr. Glasscock for her answers when she returns to the refuge).

Mystery Bird: Summer Tanager? Clay-colored Robin?

Tuesday, August 5th, 2008

A number of users got shots of the following bird this morning. Forty-five minutes of chat discussion ensued (that I missed; we really need a chat log feature). Folks seem to be leaning toward Summer Tanager (which is what I voted for, before hearing about the discussion), but at least one user is suggesting that we consider Clay-colored Robin.

Check out the images. These were taken by txbird, loughman1, txbird, vanilla, and ohiobirder, respectively.

Image 32940

Image 32948

Image 32952

Image 32953

Here’s a shot of a Clay-colored Robin that txbird found on the Web for comparison:

There’s a grayish color to this bird’s head that is really interesting to me, and that I can’t really reconcile with Sibley’s illustration of either of the birds we’re considering.

I think on balance I prefer Summer Tanager for this bird’s ID, which is a shame, since Clay-colored Robin would be a new bird for CONE. But it’s not on the Welder checklist, nor is it mentioned in the list of neotropical “species of interest” in the CONE Welder study. And really, looking at these images, it looks more like a Summer Tanager than either the web photo or the Sibley illustration of the Clay-colored Robin (a bird I’ve never seen in real life).

But either way, it’s a really interesting series of shots.

Blue-gray Gnatcatcher!

Saturday, August 2nd, 2008

Woohoo, another new species. None of the shots taken yesterday of this bird were especially great shots, but you can see enough of it for the ID: Blue-gray Gnatcatcher. Here are shots by txbird and loughlan1, respectively:

Image 31839

I wonder if the people watching the camera live got to see the bird doing its characteristic sideways tail-flicking. In any event, congratulations!

Baltimore Oriole!

Saturday, August 2nd, 2008

It’s actually a pretty old image, but this shot by robin54 from back in early May recently picked up enough votes to get an official ID as the game’s first Baltimore Oriole:

Image 1840

The color definitely has a “Baltimore” feel to it. Anyway, I’ll take it. Better late than never. Congratulations, robin54!

P.S. We now have access to the nifty new linkable pages for individual images at cone.berkeley.edu, so I’m going back to my old CONE Sutro practice of making the uploaded images clickable links. Bigtime thanks to the new development team at CONE. Please keep up the good work. πŸ™‚

American Robin!

Thursday, July 24th, 2008

We should arrange for hurricanes more often. User yan snapped the following photo that I’m inclined to call an American Robin, the first for CONE Welder, this afternoon at 2:40:

Here’s a zoomed-in version of the shot:

Looks like a Robin to me. If we get the ID, that will be two new species for the game in one day. Not bad. πŸ™‚

Update: We’ve now got the ID. Yay!
