Another Grey Bust

Tuesday, February 16th, 2010

Another 1000 African Gray parrots were discovered earlier this month in crates about to leave the airport in Cameroon for transport to Bahrain and the Middle East. This is the second illegal shipment of these parrots intercepted in two months in Cameroon. The total number of birds discovered numbers over 1500 between the shipments – all sent to Limbe Wildlife Refuge for rehabilitation. The birds who are alive and who are able to be released will be. Many have already died from being crushed or glued or just general rough handling and fear during the “shipment.”

These are all wild caught birds of the endangered species variety. They are CITES II which means trade in them is restricted because their populations in the wild are so low that they cannot sustain any trade. I spoke with Dr. Irene Pepperberg of The Alex Foundation who has done the seminal work on the intelligence of African Grey Parrots. She told me that when there is this high a number of birds being poached, it means there are a number of large flocks from which the adults are taken. Stripped of their teaching population, the younger birds remaining in these substantially decreased flocks are left trying to learn to survive in the wild on their own and it makes these diminished flocks extremely vulnerable. If any of the birds that eventually are released are young, they have an equally challenging situation in that they also need adult birds who will teach them how to survive. But in this case it’s even trickier because these unrelated birds being released will need to know to search out and find adults who are willing to teach them. Add to this the fact that, according to research done by Dr. Pepperberg over a 30 year project, African Grey parrots have an emotional equivalent of a 2-3 human child and the intelligence of a 5-6 year old human child, and seeing these birds tightly crammed in baskets and crates is even more heartbreaking.

Limbe is charged with caring for over 1000 parrots right now – a financial and time burden they never expected. The best way to stop these kinds of killing shipments is to end the market for wild caught birds. It can start with each of us. Triple check your desire for an exotic bird before buying one. Make sure you are prepared for the commitment. It can be up to 80 years of commitment and you can expect your life to change dramatically to accommodate the bird – you cannot reasonably expect the bird to accommodate your lifestyle and still have any kind of satisfying life for either of you. If you still must get one, then be absolutely certain the bird was domestically bred and raised and there are several generations of domestically bred and raised birds in his or her lineage. Wild birds make terrible pets anyway. Those domestically bred and hand raised are more accustomed to human interaction and there is generally less aggression than with a wild caught bird. We can avoid unwittingly aiding and abetting the poaching of exotic birds by shrinking the market for them. The birds are much happier when they remain in the wild. And, it would be a travesty for a regal bird like the African Grey to disappear because of his ornamental value in the pet trade.

Finch Fights

Monday, February 15th, 2010

Apparently there are no animals too small be bet upon in forced fighting rings. The latest bust, this one in Massachusetts, of illegal immigrants who keep finches in intolerable conditions, get them worked up , sharpen their beaks and then get them fighting, is a sad testimony to what goes on. Who would have thought finches weighing just grams could be considered fighting instruments with which to make money? This article in the Boston Herald tells a tough story about an improbable, but apparently not uncommon form of animal abuse.

Where’s the Water?

Monday, January 4th, 2010

Right now the northern states are blanketed in snow, and stepping outside can be hazardous. Winter temperatures can dip below zero degrees Farenheit, and the wind chill pushes far below that. We can throw on layers or stay inside, but what do the birds do? How can we help birds brave the winter onslaught of freezing temperatures and battering snow?

Birds can make it through the winter without our help, but many people provide their bird visitors with a heated bird bath.  Open water is hard to find in winter, and by providing birds with a constant source of water you will attract more birds to your yard. Some birds (not all) will eat snow, but the amount of energy it takes to process this snow into water is high.

So, you can make life easier for your backyard visitors with a watering dish that does not freeze over. You don’t need to buy a brand new bird bath – you can buy a small heater that you leave inside your current bird bath with an extension cord. But, it is a good idea to use some caution when using a heated bird bath as well. When temperatures drop too far, a bird’s feathers can freeze after taking a bath or even from the steam that comes up from the birdbath. This can be dangerous for the bird, even resulting in death.

Laura Erickson of the Cornell Lab of Ornithology has some good recommendations on how to deal with this problem. Here is a link to an article on her new book, “The Bird Watching Answer Book, Everything You Need to Know to Enjoy Birds in Your Backyard and Beyond“.

Here is the paragraph specifically regarding heated bird baths:

In a section titled “Birds Don’t Need Hot Tubs,” Erickson states: “I would never use a heated bath when temperatures were below about 20 degrees to prevent steam from coating feathers.” She recommends placing a grill made of wooden dowel rods over a heated bath to prevent bathing while allowing access for drinking. If the bird bath is frozen, Laura sets out a small plastic container of water near the bird food in the morning and brings it in when it freezes.

So, while a heated bird bath can make your backyard a winter birding bonanza, you also must keep the safety of your feathered friends in mind. Cornell has some suggestions on setting up a birdbath which can help both you and make the winter a better time for year for your backyard visitors.

A Cardinal Moment

Wednesday, December 2nd, 2009

With the changing seasons our New York City backyard garden has different birds passing through, but among our constant companions are our cardinal family. This beautifully masked male cardinal is the epitome of grace and elegance. In the summer his gorgeous coloring is eclipsed by no other bird in our garden; in the fall, even with a color change he is still quite the beauty. This morning he has been frequenting the wisteria behind our home and he looks so great mixed in with the changing leaves. Known to us as Senor Cardinal for his haughty elegance, his female companion possesses none of the patience nor self-confidence he does. She flits from branch to branch in a constant state of chirping frenzy – even with their baby having fledged long ago and no longer needing constant care. Her agitated state has ratcheted down from when the baby was fledging, but she still is one of the most excitable birds in the garden – and very difficult to get a photo of as she is a moving target. So, here is an early December homage to Senor Cardinal – sporting his ever-so-slightly diminished fall coloring. In the snow he is a standout….can’t wait!

Tiny Bird With a Big Story

Wednesday, November 4th, 2009

Hummingbirds have many challenges – they are tiny and yet need to be some of the toughest birds out there. They live in conditions where eeking out a living can be a challenge – especially when you have to feed at frequent intervals just to keep going. In the cloud forests of Peru, there is a hummingbird – the male of which has a tail that defies all probabilities of flight. The Spatuletail Hummingbird’s tail appears to give no benefit to flight which is key to how we think about hummingbird aerodynamics. The BBC filmed the mating displays of this amazing little bird struggling to impress a female. Sometimes the truth is even more interesting than anything you could ever make up.

When Once Just Isn’t Enough

Thursday, October 29th, 2009

Songbirds who migrate at night have long been thought to migrate north to breed then south again to molt and overwinter. That makes sense, right? But, the times they are a changing. Now researchers from the University of Washington have discovered that there are some birds who make a stop in Mexico on the way down south, not to rest and molt, but to start a second family for the season. Known as “migratory double breeding”, this is the first instance of it in the new World, and the first time it has been documented anywhere in a southerly migration. The species researchers discovered taking part in this were Yellow-billed cuckoos, Orchard orioles, Hooded orioles, Yellow-breasted chats and Cassin’s vireos.

The entire article can be found in Science Daily, and if you want to learn more about some of these birds, you can check out the Peterson Field Guide to Backyard Birds.

OK in the UK

Wednesday, October 28th, 2009

According to a recent survey from the RSPB published on the BBC website, some of the more rare species of birds in the UK are seeing increases in their populations while some of the more common birds are seeing declines. The increased numbers of rarer species (including the Osprey and Avocet that are seen in North America as well) is great news, but the decline in more common birds (like the Swift and Starling – which is an endemic bird to the UK and not considered a pest) is a continuing saga. Much of the trouble for these common birds appears to lie in farming techniques. And, the UK has responded by trying some experimental measures in the Natural England project – giving farmers money in return for keeping some areas fallow for nesting birds and keeping some areas lively with plants that attract insects. Not surprisingly, this appears to be creating a beneficial area for birds and other wildlife like hares. And, it has captured the interest of many farmers who profess to like watching the hares boxing and the lapwings nesting sometimes a bit more than doing the plowing or harvesting. Some great ideas are also pretty simple and we can only hope that if this does work in the UK that this example of a simple and effective means to help wildlife can find its way to implementation in other countries.

Sounds of Nature

Sunday, October 18th, 2009

Nature configures itself in interesting ways that have meaning and speak to us where we are. So it was for Jarbas Agnelli, a Brazilian musician, who saw music in the pattern of birds on wires. Letting the visual pattern the birds made on the wires be the notes, the outcome of this one photo frame of resting birds is a flight of music to anyone’s ears. Listen to the music he transcribed and think about the ethereal compositions that are visually all around us and not yet heard. There is art and music everywhere in nature. Sometimes we just have to look at things with a different eye to unlock it.

Backyard Migration

Friday, October 16th, 2009

The storms this week that brought rain and cooler weather also brought a lot of migratory birds into our city garden. Today was a busy day in the early afternoon for about an hour when one bird after another came to grab some food and a drink from our fountain. At one point the fountain had an avian traffic jam with a Robin, several Catbirds, a Hermit Thrush and three Cardinals (I believe our Cardinal family from this year), all trying to get their space at the watering hole. At one point we saw a Towhee, and that is when I got out the camera. I got out my iPhone and brought up my Peterson Field Guide to Backyard Birds app when I saw the sparrow as I wasn’t sure if it was a Chipping sparrow or White-throated. The Towhee came and went, but the Catbirds, Sparrows and Hermit Thrush all stayed close by the window for their close-ups.

Identifying Birds of Prey the Peterson iPhone Way

Tuesday, October 6th, 2009

Migration season is in full swing for many raptors and there are hawks and falcons flying overhead – in some cases in large numbers. I love watching these birds during migration if for no other reason than sometimes there are huge numbers of them. I was in Panama several seasons ago and the hawks were kettling as of thousands of them flowed into a tight formation to stay over land, battling for space over the isthmus of Panama. It’s like when the superhighway suddenly loses a lane and all the cars back up because they have to change the traffic flow to accommodate fewer lanes. And it is a boon to hawk watchers.

Recently I was watching a trio of hawks just enjoying the currents overheard. I still find identifying hawks a challenge and so when I was creating the Peterson iPhone Field Guide to Birds of Prey (you can also use it on your iPod Touch), I wanted to have a handy guide that was easy to use and I kept in mind the things that I found helpful when trying to make identifications.

Mostly I see birds of prey silhouetted. When I look in bird field guides, the beautifully drawn images or well lit photos are great to look at, but in the field, they are not always as helpful. Peterson has available silhouettes for each family of raptor, so we used those to identify the family each bird is in. That generally is my first place to look – get the shape of the body and wings, and this narrows it down a lot.

Once the family is found (and they all are fairly distinct in silhouette), the next thing I look for is the overhead shape and color. We took the beautifully drawn Peterson overhead images and made them part of every individual plate for the birds for which they were available. So, you can touch the name of each bird in the family you are after and check the overhead view to see if it looks like what you are looking at – pale or dark, distinctive markings, maybe a window in the wing…things like that.

If I am still not sure at that point, even though I probably have it narrowed down to only one or two, then I touch the information icon on the app on the birds in question so I can see the text. Sometimes there is identifying information in there that is not quickly visible in the image.

A final identifying opportunity is if the birds are vocal, then I can look at the birds I have it narrowed down to and listen to each of their calls to compare. Often this is the best confirmation for me that I have the right bird. The whole process generally doesn’t take much time because it is really simple to move between birds in a family and to get information on each bird quickly by touching the buttons at the bottom of the screen. And, because the app is resident on the handset of your iPhone or iPod Touch, there is no need for an internet connection. I also always have my phone with me, so I am never without a quick and accurate identification tool for birds of prey.

To make it easier to learn to identify birds of prey quickly, we designed a quiz that gives you the choice of learning birds of prey either just by their sound or by sound and image. It’s a multiple choice quiz and it is fun to do and a good way to learn the different birds of prey. Even people who are not serious birdwatchers love this. Who doesn’t like hearing the calls of raptors? Some are such a surprise!

One of the cool things about this iPhone app is that not only can it help with identification, but it also helps raptors at the same time. My company, Wildtones, supports a variety of wildlife and animal charitable organizations, and we were delighted to be able to team up with our friends at The Peregrine Fund which is a leader in conservation and research for birds of prey. We donate 5% of the profits from the sale of the Peterson iPhone Field Guide to Birds of Prey to The Peregrine Fund and we hope to be able to continue to help supporting their really great work for some time.

If you have any questions or comments about raptor watching or this app, we’d love to hear from you! Oh, and BTW, no matter what iPhone or iPod Touch you have, this app will work on it.
