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.

Innocent Bystander

Sunday, January 31st, 2010

The Chicago Tribune wrote this story about a hawk who had gone to her roost for the night, expecting to have a cool but quiet nights rest. Sadly for her, she was sleeping in a tree that happened to be near the location where a small plane crashed, killing both passengers. Upon impact, the plane exploded in flames, and the hawk was blasted from her roost to the ground – the blast burning off all her feathers. Most news reports would have reported the fatal crash and left it at that tragedy. But in this case, one of the police officers on the scene saw a bird standing in the snow not far from the wreckage and had the compassion and presence of mind in the turmoil to call someone to rescue the hawk which had been badly burned but was still alive. It’s a good reminder that sometimes the end of the story isn’t really the end. Bravo to the police officer who found the bird and thought to call for help for her, rather than to just leave her in the snow. And thanks to Dawn Keller of the Flint Creek Wildlife Rehabilitation Center for taking her in and caring for her. As a result, the crash which was a terrible tragedy was not a complete one, and this innocent bystander – nicknamed “Phoenix” – now has a chance at survival.

A Cozy Warm Bed

Thursday, January 7th, 2010

Do you ever wonder where birds sleep? On a cold winter night, when the wind is blowing the snow sideways across the light of your street lamps, the chickadees that visited your feeder in the morning are huddling close together. Hopefully they have found a decent cavity to roost in. If your neighborhood is like mine, a dead tree is considered a hazard and is quickly removed to prevent damage to houses. The valuable cavities in a dead tree are eliminated in most urban and suburban areas where dead trees are not allowed to stand.

What can you do for the local birds that are looking for a place out of the frigid cold? Consider a roost box. While a nest box is flat inside and provides room for a nest, a roost box has a series of pegs that serve as perches with a roof overhead. Roost boxes are designed to provide a simple shelter for birds where they can sleep together with some relief from the cold and use their collective body heat to keep warm. Roost boxes often look very similar to nest boxes. Different size entrance holes provide shelter for different types of birds. A smaller hole invites smaller birds, such as sparrows, nuthatches and titmice, while a larger hold can accommodate flickers and small hawks. Smaller birds loose body heat very fast, but in a roost they can keep each other warm by staying close together.

Owls can use the same box they nested in as a roost box in winter. Other birds, such as chickadees, can roost in a PVC pipe roost that you can easily make yourself. Click on the picture for simple instructions on how to build a chickadee roost.

Here is a great website from Audubon Society of Omaha that provides instructions for those of you who would really like to build your own roost boxes, and nest boxes too.

While a bird feeder may provide the wintering birds with food, they also need shelter to make it through the winter. Roost boxes can help attract more birds to your area, and can keep them warm and safe through the cold nights.

If you want help identifying the birds around your backyard, check out Peterson Field Guide to Backyard Birds 2.0 for iPhone and iTouch. All the great illustrations and information available in the original Peterson Field Guide book, but adapted for your iPhone or iPod touch. It’s easy and fun to use, and it can help improve your birding skills, no matter what level you are at. With a roost box in your yard and Peterson for iPhone to help identify your backyard birds, you’ll enjoy a winter of birding.

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.
