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!

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.

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.

Will the Bird Friendly Shade Grown Coffee Please Stand Up?

Thursday, June 4th, 2009

My husband and I are coffee drinkers. In fact, recently I made the mistake of taking him along to help get a replacement when our old cappuccino machine died. We wound up with a machine so complicated I needed an advanced degree to make it work. But I digress. The reason for my writing about coffee at all is that for many years I have been looking to find coffee which is bird friendly, which means it is grown in the shade. Why is growing coffee in the shade important you might ask? Much of the coffee we buy is grown in neo-tropical countries where birds we see in the spring and summer spend their winters. So when that yellow warbler leaves your backyard and heads to Central America, he starts his journey with the full intention of having a place to stay and food to eat when he arrives in his winter home. Since it is cheaper and easier to grow coffee by clear cutting the land of all trees and shrubs, this kind of agriculture is a very bad thing for the birds which migrate to these areas as well as the other wildlife which live there. Exhausted after a grueling trip south, battling hurricanes and all kinds of challenges, increasingly more often, migratory songbirds are reaching their traditional overwintering grounds and finding they have been clear cut or destroyed. Coffee is naturally a shade loving plant, but since it is cheaper to clear cut the growing area and then just treat the coffee plants with chemicals to keep them going, this has become the new norm for larger agricultural enterprises. So, if we want to help migratory birds (and other animals, too) keep their populations up by retaining their habitat intact and chemical free, buying shade grown coffee which is grown on plantations which retain the trees and undergrowth necessary for songbirds is an easy and practical solution.

Or so I thought. Coffee has many descriptive terms. It can be fair trade (which guarantees poor farmers in co-operatives a fair price for their coffee), organic (which refers to the use or non-use of chemicals), and (among other descriptive terms) shade grown. What I have come to discover is that shade grown can mean many things and these various terms are often mutually exclusive. So that if it is fair trade and/or organic, it may not be shade grown. And there is shade grown and then there is bird friendly shade grown. Until recently, even finding shade grown coffee was a challenge. You had to trust that the distributor really did buy coffee grown in the shade, if the shop even had any idea what you were talking about. I thought I had found a great shade grown coffee, and have been using it for a very long time, only to discover that it most probably is shade grown but not bird friendly.

I learned all this from Scott Weidensaul who really opened my eyes to what to look for. He told me that normal shade grown means they did not clear cut the trees. However, they do clear the undergrowth and so it causes a mono-culture of trees and coffee bushes. This is only mildly better than coffee grown in clear cut areas. Bird friendly coffee growers not only retain the tree canopy, they also keep the undergrowth which the birds need for food and shelter. Smithsonian has the only 100% organic bird-friendly coffee certification and their certifications are given only to growers who comply with a fairly rigid list of standards. The coffee is better tasting, too as it has no chemicals and ripens more slowly. You can buy Smithsonian bird friendly certified coffee at Birds And Beans which was founded by a group of concerned naturalists and birders including Kenn Kauffman. So, spread the word that buying bird friendly certified coffee is an easy way to help migrating birds as well as wildlife. Whenever biodiversity can be left intact, we all benefit from it.

So, now in my new complicated coffee machine, I have the real deal being brewed. Real bird friendly shade grown Smithsonian certified coffee. It makes a better cup of coffee if for no other reason than it really is an easy change to make in my routine and has such a wide-ranging benefit to so many birds and animals. Now that’s the best way to start the day!

Oh, and in case you thought that it was just the warblers who are affected by loss of habitat through coffee growing, think again. Here is a list of some of the species who return to or migrate through shade grown coffee plantations and who benefit from us taking a moment to think before we buy coffee:
