Sharpen those pencils…for the gnatcatcher!

June 30, 2014

Please read the article on page one of LATEXTRA in this morning’s L.A. Times. Another assault based on dubious science by the Pacific Legal Foundation, the organization that believes that developers have a constitutional right to build wherever and whatever they wish, no matter what the damage caused to nature or other people.

A comment period will be announced by the US Fish and Wildlife Service and I hope each of us delivers a letter or postcard supporting the protection of the few California Gnatcatchers that survive to this day. Stay tuned for updates.

My new binoculars

June 29, 2014
by

I just got a replacement pair of binoculars for my old Zeiss “Diafun’s” and I went to my stack of unread or un-acted-upon items that seems to permanently decorate my desk. There I found a copy of the Cornell Ornithology Lab’s Fall 2013 article on the birding binocular evaluation that Steven Zax generously handed me in November.

Cornell doesn’t go through the process of evaluating binos very often. The last bank of test was five years earlier, and as pointed out in the article, there have been many changes in equipment and prices since 2008. So, if you are in the market to replace your current pair, or to know what you would get in case of a loss or accident, the articles are worth reading, and Cornell generously puts them on line for you at no fee.

ZeissTerraED

A few notes about their conclusions.

1. You can spend nearly $3,000 including sales tax for the best of the best nowadays.

2. Their basic advice (Jessie Barry and Ken Rosenberg are the authors of the main article) is to buy the best you can afford. I disagree, or put it differently. I would say the best you can afford to lose or break.

3. There are a lot of good binoculars available under $700 now.

4. There are no under-$100 binoculars that will satisfy a serious birder.
To read all the information, go to http://www.birds.cornell.edu/Page.aspx?pid=1642&q=best%20binoculars
[If the above link is broken try: https://www.allaboutbirds.org/news/the-cornell-lab-review-affordable-full-size-8×42-binoculars/]
You will find a whole lineup of links to the binocular review including the main article, Ken Rosenberg’s explanation of how to make a good buying decision, and the results of the evaluation in a table version.
It turns out for me that the replacement for my Diafun’s is a pair of Zeiss “Terra ED’s”, slightly heavier, brighter, and amazingly sharp edge to edge.

Happy birding! Feedback welcome.

Apps Anyone?

June 28, 2014
by

For those who have a smartphone or a pad, I recommend you quickly go to the Nature Share page of the iTunes store or Google Play. Four of the best Audubon apps are available for $1.99 each through the 4th of July weekend. These are photo guides and I find the apps far superior to the book version of the same title. I was especially surprised at the number of bird vocalizations on my California Birds app.
I only look at the butterflies app occasionally but it’s great having it in my pocket for those occasions. Check carefully. Not all apps are available both for iPad AND Android.

Malibu Lagoon Trip Report: 22 June, 2014

June 26, 2014

June seems to be when many people decide that birding looks like fun. When they show up at the lagoon I always feel both sad and hopeful – sad they selected SoCal’s slowest month for birds; hopeful they won’t be discouraged and quit.

I always let them know that after June the birding can only get better. We had 465 total birds in 43 species – typical for June; compare that to Oct’13 (1671 & 75 species, or Feb’14 (1564 & 59 species). SoCal hosts a lot of migrant and wintering birds; breeding bird populations seem sparse in comparison. Of course, if we ever see the long-awaited publishing of L.A. County’s breeding bird atlas, we’ll know what’s what.

Checking results on the bocce ball green (R. Ehler 6/22/14)

Civilizations rise and fall, yet bocce ball remains. (R. Ehler 6/22/14)

After wandering around the perimeter of the channel, out to the beach and on to Adamson House, we found two old men (I’m old, so I’m able to call others old) playing bocce ball on the lawn. The slope of the lawn towards the beach caused their bowls to significantly curve, a fact to which they had not yet adjusted, so we – or maybe it was just I – gave them a hard time about it, as a form of encouragement of course, of course. It looked like fun, and it struck me that it could easily be one of the most primitive forms of game known to humankind, the ancestor of countless other games and sports. What could be simpler than tossing or rolling objects, trying to hit a target? Acorns or pebbles serve as well as perfect spheres; you don’t even need an opposable thumb, as one player pointed out. I’ve seen monkeys in trees pelt humans below with – ahem – stuff, a practice at which they are acknowledged to be very unpleasantly skilled. [Note: Wikipedia says you can toss or bowl the bocce ball; the game goes back at least to Ancient Rome and Greece, and probably Egypt before that.]

Juvenile & adult Crows (R. Ehler 6/22/14)

With the exception of a Phainopepla – a new lagoon record for me – perched in a tree near Adamson House, we had no new birds for the season. Instead we had various breeding birds busily gathering food or shepherding their young: Gadwalls, Mallards, Killdeer, Black Phoebes, American Crows, Barn Swallows, Mockingbirds, Song Sparrows and House Finches, among others.

Young Barn Swallows prefer a perch that sways (R. Ehler 6/22/14)

After the birdwalk we held our annual picnic at our favorite site in Tapia Park, a few miles up Malibu Canyon. It was very quiet, except for Mockingbirds, California Thrashers and California Towhees tootling away, and very pleasant in the live oak shade. After eating some great food we played “Bird Bingo,” which works much like regular bingo except, as one might guess, with bird pictures instead of letters. The birds were from all around the world, so you might find a Shoebill next to a Song Sparrow, an unlikely event in the real world. Winners won bars from Ellen’s cornucopia of world chocolate.

10-year comparison summaries are available on our Lagoon Project Bird Census Page.    [Chuck Almdale]

Note: Beginning July, we will return to our pre-project form of bird list, which will report most recent 6-month periods. Two years of tracking census data in this format has amply demonstrated that the project, even during its messiest days, had no ill effects on bird life, despite the claims of the few, but very vocal, complainers.

Full Strawberry Moon Update – 12 June, 2014, 9:11 PM PDT

June 11, 2014

Here’s another update from SMBAS Blog on that large, disc-shaped, shining object which has frequently and mysteriously appeared in our nighttime sky this year (known to many as the moon).

[Note: I found the above beautiful photo, by professional astrophotographer Göran Strand, on the NASA website. See many other of Göran’s astonishing photos at http://www.astrofotografen.seOn Friday the 13th, strangely enough, the moon rising over our Mt. Piños campsite was the same lovely rose-pink color.]

June 12, 9:11 p.m. PDT — Full Strawberry Moon.   Known to every Algonquin tribe; strawberry picking peaks during this month. Europeans called it the Rose Moon.  [Top 10 Amazing Moon Facts]

Santa Monica's Summer Solstice Sunset over the Santa Monica Mountains (Bob Gurfield 6/21/14)

Santa Monica’s Summer Solstice Sunset over the Santa Monica Mountains (Bob Gurfield 6/21/14)

Long-time SMBAS member, prominent kayaker and alert reader, Bob Gurfield, reminded us of the fact that “Those of us who rise when the sun comes up should know that the latest (and earliest) sunrises do not occur on the solstices. ”

Santa Monica's Winter Solstice Sunset over the ocean (Bob Gurfield 12/21/13)

Santa Monica’s Winter Solstice Sunset over the ocean (Bob Gurfield 12/21/13)

With use of information from this site we constructed the following chart detailing sunrises & sunsets for three locales – Los Angeles, Anchorage and Bogota (Colombia).  Note that the “earliest’ time (either sunrise or sunset) always precedes the solstice. The closer you are to the equator, the longer the period of this earliest-to-latest date spread.  For example, around the summer solstice, Bogota, Colombia has 57 days between its earliest sunrise and latest sunset, Los Angeles has 16 days, Anchorage has only 3 days. Also note that the longest-to-shortest-day spread is very small near the equator; the difference for Bogota is only 32 minutes, 5 seconds. This is why in the tropics winter & summer are replaced by wet and dry seasons.

Nowhere do the latest sunrise and sunset or earliest sunrise and sunset occur on the solstices (except perhaps exactly at the North or South Pole).   The reason for this is that the earth’s axis is not aligned with the minor axis of the earth’s orbit around the sun.   Over time the earth’s ecliptic precesses a tiny bit each year so that every 134,000 years the orbit makes a complete rotation with respect to the positions of the stars.   [This is not the same as the ‘precession of the equinoxes.’]  http://en.wikipedia.org/wiki/Apsidal_precession

The next significant full moon will occur on July 12, 4:25 a.m. PDT.   Keep an eye on this spot for additional late-breaking news on this unprecedented event.
