Arboretum spring bird walks coming up!

As we turn our clocks forward inviting in the spring it’s a good time to plan ahead for a bird walk or more in the Arnold Arboretum.  Here is this year’s schedule, presented with some images of birds likely to be seen and/or heard on each walk as the spring migration proceeds:

Saturday April 20— Meadow Road to Bussey Hill:  A 90-minute walk suitable for beginners as well as more experienced birders. Meeting place: Inside the main gate off the Arborway (parking along the Arborway) .  8:00 a.m.

How many birds in the whole wide world?

Some time ago I got a question from a six year old about birds.  It’s the kind of question that many people might wonder about, but only a six year old would ask it. “How many birds are there in the whole wide world?”, Harry, who lives in Somerville, MA, asked.  I took a crack at it and this is the result (full disclosure: Harry shares a lot of my DNA).

Dear Harry,
You have asked a hard question and I will give it a try, but it is a LONG answer. The hardest question is the biggest—how many birds in the whole world? We are not even sure how many different kinds of birds there are in the world. The answer to that is about 10 thousand. Several of these kinds, or species, are numbered over 3 billion in the world. Probably the most common, if you don’t count chickens that we raise for eggs and food, is the House Sparrow.

There are lots of kinds of birds that are very common, including some sea birds that spend their whole lives flying around the ocean except when they are having babies on some tiny island. That makes them very hard to count correctly. All together the total number of wild birds in the world is somewhere between 100 billion and 400 billion! The fact that there is such a big difference in those numbers shows how hard it is to count them all.

Even though there are a lot of birds in the world, you should know that there are some birds that are very rare. Scientists call them endangered, which means that if we are not kind and helpful to them they might disappear.  For example one bird that lives in the forests of Brazil in South America, the Stresemann’s Bristlefront, has gotten so endangered that there are only 15 of them in the whole world!

The estimate for the total number of birds in the United States is around 10 billion in the spring but more like 15 billion in the fall after the babies have hatched.

Right here in Boston I can give you the EXACT number of birds that were present (or at least seen) in Boston on Sunday December 16, 2012.  That was the day that a whole bunch of birders spent all day going around places like Jamaica Plain and Somerville counting every pigeon, every sparrow, every goose and every cardinal and writing it down.  Here is a funny little fact about the Boston Christmas Bird Count (BCBC)—which has been going for more than one hundred years—the very center of that circle is the Healy School playground in Somerville!  So some day you can go with your parents and stand in the very center of the BCBC counting circle for birds and see how many birds you can see, That game is called a “Big Sit” among us crazy birders.

Anyway, here is the report of the count of birds reported that day in December, listed by species (the rare ones are CAPITALIZED):

Boston Birders
The 40th Greater Boston Christmas Bird Count (actually the 112th—Belmont, Jamaica Plain and Winchester have been covered since the very first CBC in 1900!) was held yesterday (Sunday, December 16) under some difficult weather especially after the noon hour. That did not damper the 102 observers in the field.  The total number of species recorded was 125 plus SEVEN count week species (listed as CW)

We added TWO new species to the overall count—SORA RAIL and PAINTED BUNTING bringing the historical count to 228 species—AMAZING for an urban count. We had six new high counts (listed as HC) Highlights are capitalized and a brief location is indicated.  Photos of  many of these birds will be sent for documentation to National Audubon Society.

You will have to get some help from your mom or dad to add all those numbers up.  Papa is too lazy for that. But you can see that on that day there were over ten thousand starlings counted which was way more than the House Sparrow at only 3,324. Maybe next year you can help us count all the birds, starting from the very center!

I hope you like this very big answer to a very big question

Rare Birds & Odd Ducks at Jamaica Pond

In my first Jamaica Pond Ducks post I covered the more common waterfowl likely to be seen on Jamaica Pond.  Here I will discuss less common ducks and other birds attracted to the Pond, especially in the fall and winter.

When we think of loons, we imagine being on a tranquil lake in upper New England and listening to their melancholy call:

That is indeed where many nest, but for the rest of the year they move about on both salt water and fresh.  This Common Loon, wearing its winter plumage rather than the classic summer tuxedo, hung out on Jamaica Pond for at least six weeks this winter. As the Pond began to ice up in early January, it departed:

Just recently, another member of the loon family appeared on the Pond—an immature Red-throated Loon.  It never got close enough to the shore to allow for a photo op.

There have been a number of “vagrant” ducks seen on the Pond over the last decade. This winter we had several spectacular ones:

Northern Shoveler, male.  This was one of three on the pond in late November 2012.

Northern Shovelers are well named for their very wide bill, built for scooping along the water’s surface to pick up small invertebrates or bits of vegetation.  In 2002, one of them ran afoul of urban bad habits in the Muddy River’s North Basin behind the Museum of Fine Arts in the Fenway, probably because of that feeding pattern:

This poor duck managed to get a Gatorade cap ring in its bill and up over its head, and couldn’t get it off.  My friend Andrew Joslin and I—equipped with waders and nets—tried several times to capture and free the duck, but it wouldn’t let us get close enough.  The Animal Rescue League attempted to net it from a canoe and also failed.  After being in the area for more than a week it disappeared.  We presumed it died, since the plastic “bit” didn’t allow it to fly more than short distances.  The event is a poignant reminder to dispose of your trash properly.

The avian genus Aythya is represented by six species in Massachusetts and five of them have been recorded on the Pond.  The most commonly seen is the Ring-necked Duck:

P1030697

These handsome ducks should have been called “ring-billed” due to the white ring around their bill. The bill marking is far more distinctive than the chestnut neck ring, found on males and seen only at close range.  One or more Ring-necks have been seen every year recently on the Pond.  On the other hand, the Canvasback—the largest of the Aythya group—was documented only once before in this century until two males arrived in January, departing less than 48 hours later.

P1030762

As in many duck genera, Aythya females are much less intensely patterned than the males, which makes them harder to identify.

P1030831

The last of the Aythyra genus which appear on the Pond occasionally in winter are the Scaups, Greater and Lesser, the latter more commonly.

A small diving duck that occasionally visits the Pond is the Bufflehead.  They are never numerous on the Pond—usually appearing singly or as a pair— whereas in salt water settings there may a sizable raft of them.

Another water bird is common on the Pond much of the year, but is rarely seen in the winter:

P1260810

Double-Crested Cormorant. These birds often hold this position, thought to be for drying out their feathers which are less waterproof than most waterfowl.

A close-up of this bird seems to hint at the reptilian origin of birds, possibly arising from an ancient bird named Archaeopteryx:

In my view, the most beautiful duck on Jamaica Pond is the Wood Duck.

Wood Ducks prefer sheltered water closely surrounded by trees; they appear nearby most frequently along the Riverway.  They are cavity nesters and some volunteer stewards of the Emerald Necklace have recently put up nest boxes at Leverett Pond and Ward’s Pond  downstream from Jamaica Pond to try to encourage nesting. So far there have been no takers.

Finally I should mention another bird that everyone recognizes when they arrive— Mute Swans.  Mute Swans were imported from Europe in the late 1800s as decorative waterfowl on city ponds and estates and so are not native.  They have multiplied rapidly in the wild and with a voracious appetite and an aggressive attitude they are now considered an invasive species.  They will chase other waterfowl and even people. Here is one getting in your face:

In the past The Boston Parks Department used to bring a pair of swans to the Pond—as they continue to do at the Public Garden— but most recently the Mute Swans seen here are part of the wild population. This winter there were two birds on the Pond most of the time.  In December 2009 at least eleven were recorded.  They can be a haunting sight in the fog of a winters day:

Debate continues about how to control these waterfowl—the largest birds in Massachusetts—as they spread throughout the country.  In the meantime enjoy those few that come to our local waterways, but show them some respect.
