Super Shield

Zen and me

Back in October I got to spend just a bit of quality time with Zen, FCWR’s education Cooper’s Hawk. Due to their high-strung nature, Cooper’s Hawks aren’t often kept as glove-trained education birds.

Sitting with beautiful Zen, I couldn’t help staring at his piercing eyes and his super-cool superciliary ridges.

The superciliary ridge is also known as the supraorbital ridge. It’s that bony shield above the eye, kind of like a brow line on steroids, that gives many raptors a sort of “angry bird” look. The ridges serve to block out glare from the sun. They also provide protection to the eyes. Pretty neat to see close-up, yes?

Key West’s Audubon House

Audubon House, Key West
Audubon’s Brown Pelican detail

The Audubon House in Key West is a bit of an odd attraction. The home was built in the late 1840s by Captain John Geiger, a pilot who became rich by salvaging vessels that wrecked along the Florida Keys. The home was saved from demolition in the late 1950s and eventually became a public museum, dedicated to commemorate John James Audubon’s visit to Key West. That visit took place in 1832, when the artist apparently met with Geiger and other Key West notables. He could not have visited the house, but he may have been on the grounds.

It’s a lovely home, restored to how it may have been during its prime in the mid 1800s. The rooms are furnished with period furniture and Audubon prints. The link to John James Audubon may be a bit tenuous, but we did enjoy our visit back in September. It’s always nice to see original Audubon prints, anyway.

Mystery Leftovers

Arthur spotted something on the railing as we were walking along the boardwalk at Lake Ashby the other day. “What’s that red thing?”

A pellet, that’s what! I wanted a closer look so I picked up a stick and went back to the pellet for a little dissection. It was reddish-orange. It looked like there was some shell or exoskeletal-type material. And crab legs?

There were two tiny round white shells. At first it seemed like the bulk of the red-orange stuff was plant-based, but as I sifted through it seemed more like it all consisted of crustacean exoskeleton. That makes sense… plant stuff would more likely just pass on through, I suppose. There were quite a few tiny crab legs.

I wish I had taken a photo with a coin or something to show scale. I guess the intact pellet was about 5cm long.

The pellet was in a very exposed area, on boardwalk railing over Lake Ashby. I took this picture after opening up the pellet — see the reddish area on the railing?

Lake Ashby boardwalk

Here’s another view of the boardwalk at Lake Ashby.

So my big question is: what bird cast this pellet? I had a few guesses so I looked up some species accounts on Cornell’s Birds of North America Online (BNA). In many species, information regarding pellet-casting is not mentioned or it is acknowledged as being unknown. What would eat a bunch of crabs and then hang out on an exposed boardwalk railing long enough to produce a pellet?

After checking the species accounts of several duck species (not much data or no pellet-casting), various water birds (Double-crested Cormorants tend to cast pellets at roosting sites), and a bunch of waders (Great Blue Heron pellets tend to have hair in them; Tricolored Herons eat mostly fish; etc), the pellet-casting data of the White Ibis kind of jumped out at me: Non-digestible hard parts, such as fish bones, arthropod exoskeletons, and crayfish gastroliths are cast in pellets.. Did someone say crayfish gastroliths? That’s what those little white “shells” in the pellet appear to be. I can’t be sure, but White Ibis seems to be good candidate. We saw a few Little Blue Herons during our walk, so that species was my first guess, and I still think that is also a likely candidate. Both species of Night-Heron are also possible. I would love to hear suggestions from anyone else, though. Have you ever found a pellet like this one? Do you know who cast it?

Just over the border (county birder blues)

On October 19th, while Arthur and I were visiting my parents in northern Illinois, a Scissor-tailed Flycatcher was reported at the Willow Hill Golf Course in Northbrook. As this was just about 30 minutes from my parents house, we hopped in the car and headed out for the bird, which would be a lifer for us both. The bird proved easy to find, and though the sun was close to setting, I managed to take a record shot.

just an eBird record shot

I had set a little goal to try to find 100 species of bird in Lake County for the year. I had gotten to 83 in May and by October 19 I still needed two more birds. As we set off for the Northbrook flycatcher, I had it in my mind that I’d be adding not only a lifer, but a county bird, too. Northbrook borders Lake County but as we drove across Lake-Cook Road on our way to the golf course I realized the flycatcher was firmly in Cook County. Three miles firmly. A crazy county-birder thought, yes, but I was a little bummed as we crossed into Cook.

We returned home at the end of October, and on November 2nd I was happy to learn that a Scissor-tailed Flycatcher was seen in a Volusia County portion of Merritt Island NWR. Arthur and I headed out late in the afternoon the next day. We didn’t know exactly where to go but thanks to some help from a pair of extremely nice birders who were on the same twitch, we were able to see the flycatcher. Again it was late in the day and the light was poor, but I managed a record shot.

just an eBird record shot

I had been using BirdLog to enter my bird sightings as we walked from the parking area to the spot where the flycatcher was seen. In the end my list had 21 species on it. I asked Arthur to mark the spot where we saw the flycatcher using his iPhone map. ARGH!! I had to split my eBird list. Twenty for Volusia. The flycatcher was .4 miles over the border, in Brevard. Bummer x2.

Too Full To Fly

Because vultures are never sure where their next meal is coming from, they are known to gorge themselves — sometimes, so much so that they become too heavy to fly. I’ve never witnessed this myself, but a lucky tourist visiting the Hoedspruit Endangered Species Center in South Africa captured some interesting footage of a vulture in trouble. The bird appears to play dead in order to avoid being attacked by a pack of wild dogs. Once the dogs move off, the vulture works to unload some of its extra weight so it can finally fly away from the dogs.

Down with Red Tape, Up with Barn Owl Boxes!

I’m so proud of Lake-Cook Audubon for getting Barn Owl boxes installed at Illinois Beach State Park! I know it took a long time to get there, but the boxes have been installed thanks to the hard work of club members. Here are a few photos of the installation. All photos by Sonny Cohen, posted with permission.

Sonny also posted a video of the box installation, which you can view here: Barn Owl Nest Box Raising. Barn Owls are an Illinois state-endangered species. A nearby county has a reintroduction program and it is hopeful that Barn Owls will find and use these boxes, which have been placed in ideal Barn Owl habitat. Yay!

It’s Not Rocket Science

Last week Arthur and I visited the Nature and Technology exhibit at the Kennedy Space Center Visitor Complex (KSCVC). We hadn’t been inside the exhibit space for quite a while; access to it had been restricted during construction projects related to the new Atlantis exhibition building. Nature and Technology is across from the Rocket Garden; notice the reflections in photo below.

Nature and Technology

The first part of the exhibit is devoted to early human interactions with the area now known as the Space Coast. Native American history, pioneer life, citrus farming techniques, and other topics are covered via posters and artifact displays.

history!

The historical exhibits weren’t familiar to us from previous visits, and we later learned that it and the rest of the Nature and Technology exhibit had recently been updated. For the nature portion, a short boardwalk runs through several of the different habitat types found on Merritt Island. Each habitat is accompanied by informational signs, materials to mock up the particular habitat, and stuffed animal specimens.

nature walk

While the mock nature walk is fairly standard on first glance, we noticed some unfortunate errors and inconsistencies on the new signage. The first one we noticed was a three-time loser.

Lagoon poster

no, and no

Northern Pintails

MOTTLED DUCKS are not BLUE-WINGED TEAL (photo) are not NORTHERN PINTAILS (specimens). The specimens and photo are all quite lovely; shame they are not marked correctly! The specimen marked (3) is a GREAT BLUE HERON, so just the photo, which depicts a TRICOLORED HERON, is in error there.

The next thing that jumped out at us was a sign which read, well, see for yourself:

Gull ID help

Maybe I am being extra nitpicky by letting this bug me on two levels: 1) there’s no such thing as a Sea Gull and 2) why are they going generic on the signs, suddenly? My first guess is that this is a Lesser Black-backed Gull (yellow legs) but I suck at gulls so that guess isn’t worth much… Help from the Flickr Bird Identification Help Group suggests this is a Great Black-backed. Anyway, here is the accompanying specimen:

Gull ID help

Pink legs, pink beak with black tip — first winter Ring-billed Gull? (Thank you to Flickr user Fool-On-The-Hill for ID assistance)

The non-specifics continued down the nature walk.

Flatwoods poster

At least the accompanying specimens matched the pictures. A RED-BELLIED WOODPECKER and a RED-SHOULDERED HAWK are perched beside their corresponding numbers.

I think it is absolutely wonderful that the KSCVC has such an exhibit devoted to the amazing wildlife found on the property at Merritt Island. I always enjoy the video they play on the bus tours that highlight the refuge, and I especially love how excited everyone is when the driver pauses the video to point out the ginormous actual Bald Eagle nest that can be seen from the bus during the drive back to the bus depot. In the exhibit, the specimens and habitat displays look great. It’s unfortunate that some of the items are mislabeled. Arthur and I mentioned it to staff at the information desk as we were leaving, and our comments were taken very seriously. I don’t know if they will be able to change the signs any time soon, but with our season pass you can bet we’ll drop by the exhibit again and have another looksee.

Celebrating Vultures: IVAD 2012

IVAD 2012

Back in September Arthur and I visited Disney’s Animal Kingdom to celebrate International Vulture Awareness Day (IVAD), as we had last year. This year, most of the activities were found at the Rafiki’s Planet Watch area of the park.

There were displays about vultures, including information about vulture restaurants. In addition, the long-standing mystery of the Jungle Book vulture species identification was finally solved.

Jungle Book Vultures

At Rafiki’s Planet Watch there is a special medical exam room which allows for public viewing. Appropriately, the veterinary procedure scheduled for that morning was a routine exam on one of the park’s Rรผppellโ€™s Griffon Vultures.

A small outdoor stage hosted a short program with an education Black Vulture named Beaker.

Vultures can normally be found elsewhere in the park, too. Over at the Flights of Wonder show, we watched Audrey, a young Andean Condor, fly over the audience. Here she receives a treat from a handler. Sometimes a young King Vulture named Elvis makes an appearance.

And then there are always wild vultures, soaring over the park on any given warm, sunny day.

Kettle of Black Vultures

That’s how we celebrated IVAD this year, but I should confess — I celebrate vultures as often as I can. Yesterday I celebrated by handling a Turkey Vulture patient at the Audubon Center for Birds of Prey for the first time!


Thank you to my fellow volunteer Robert for taking this photo!

Awesome adaptation against brood parasites

Nestling Superb Fairy-wrens learn unique begging calls from their mothers — before they even hatch. Researchers “conclude that wrens use a parent-specific password learned embryonically to shape call similarity with their own young and thereby detect foreign cuckoo nestlings.” In other words, the baby birds must chirp a secret password to be fed.

Mmmmmoth!

A delicious, nutritious moth makes a nice meal for a migrating Yellow-rumped Warbler. Photos taken 17 October, 2012, at Fort Sheridan Forest Preserve in Lake County, Illinois.

Since we’ve been back in Florida, we’ve been spending a lot of time away from home. I haven’t seen any butterbutts in the yard, but I haven’t had much opportunity to look. Hopefully that will change very soon! It’s always a pleasure to see Yellow-rumped Warblers in the yard!
