Flammulated Owl in the Northern Sierras

Flammulated Owl – Movements

Adult Flammulated Owl in the Sierra Nevada Mountains

Flammulated Owl is a spring and summer resident throughout the California Sierra Nevada Mountains. It is the second smallest owl in North America, and smallest of the eared owls. Only the Elf Owl is smaller. It is also the most migratory owl in North America. This owl completely leaves the US every year for its winter haunts in Southern Mexico and Guatemala.

Flammulated Owl – Size and Habits

The Flammulated Owl is just slightly larger in size than a House Sparrow. Quite often it is 30 to 40 feet high in thick pines. Being dark brown in color and having a very ventriloquial call it is difficult to locate. The strictly nocturnal Flammulated Owl can be extremely difficult to get good looks at in the darkness of night. This is further complicated by the fact that it is almost completely mute outside of its breeding season. That time is not now. It is vocal for about a month between mid-May and mid-June.

Garter Snake vs. Vole

A Mountain Garter Snake captures a California Vole.

We’ve written before about the featherless joys of birding (Desert Bighorn Sheep, Western Zebra-tailed Lizard) – those occasions when being out birding puts us in the right place to see other animals doing what they do. So on a recent Sea & Sage Audubon trip to the eastern Sierra Nevada, we were treated to the spectacle of a garter snake that had just captured a vole.

Gray Thrasher: 1st US Record

Gray Thrasher at Famosa Slough August 2, 2015

Gray Thrasher is a non-migratory endemic to Baja California, so when Sunday afternoon on August 2, 2015 was interrupted with a report of the first US occurrence in San Diego, we had to make the 75 mile drive and take a look.

Finding the Gray Thrasher

The Gray Thrasher was found by John Bruin, Lisa Ruby, and Terry Hurst at the southwest end of Famosa Slough. This area has had its share of rarities, including Bar-tailed Godwit. Once we arrived and parked, we quickly found a couple of dozen birders standing around. Others were searching for the bird in other parts of the area. We learned where it had been seen (about 45 minutes before our arrival) and which way it went. Since it obviously wasn’t where everyone was standing, we decided to look around. Just after our fourth pass by a large lemonade berry bush, someone spotted the Gray Thrasher deep in the foliage. Birders surrounded the bush looking for a better angle. All of a sudden, the thrasher decided it was hungry and came out onto the slope to forage in the leaves and twigs only about 15 feet away from us. That was too close for my Kowa TSN-884, but just right for binoculars.

Fireworks: 4th of July 2015

Happy 4th of July 2015

This year we stayed close to home to watch the 4^th of July 2015 fireworks. Walking to the top of the hill that is next to our local high school we were able to see several fireworks displays from one place. The beauty of our local 2015 firework shows were quite impressive and certainly worth an attempt at taking nice photos of. Since I had tried taking photos of the fireworks last year I figured my 2015 firework photos might be a bit better. As it turns out they are!

How to Take Fireworks Photos

So for you guys out there that want to take photos of the fireworks here is what I did. Last year I shot the fireworks at ISO 200. This year I brought that down to ISO 100. Last year I shot the photos at f/8. This year I shot my photos at f/11 to get better depth of field. Both years I shot using a bulb setting so I could vary the shutter time. Last year the photos we taken mostly from about 3 to 6 seconds exposure time. This year most of my shots were taken with a 6-10 second exposure time.

Our 4th of July Greeting

Hope you enjoy the pictures and that this year will continue to bring many outdoor viewing opportunities. A good pair of binoculars and or spotting scope from Optics4Birding makes the viewing experiences of life more enjoyable. Happy 4^th of July to you from all the Optics4Birding staff.

Happy birthday United States. We at Optics4Birding have great hopes for both our people and nature. Both are tied together. In order for us to stay healthy, the world of nature also need to stay healthy. Getting outdoors to see the fireworks is a good start for the remainder of the year.

Puerto Rican Birds

Mid-April we took a trip to Puerto Rico to see the Puerto Rican birds and wildlife. As expected, the weather was warm and humid. Luckily we did not run into any rain at all, which made for a very productive nature watching adventure. The birdlife was abundant. The coastline and rainforests were absolutely beautiful. There are 18 endemic species of Puerto Rican birds and 30 endemic reptiles and amphibians. Our main interest was the birds. We did, though, run across some of the of the other endemics too. I am sorry to say that there are also 13 wildlife species that have gone extinct. One of these was a Puerto Rican Barn Owl that I would have really liked to have seen. Several threatened species are in jeopardy. Continue reading →

Yosemite Owls

We took a very brief trip (2 nights) during mid-May to see the Yosemite owls. We principally timid our trip to correspond with the peak calling period of the Flammulated Owl. Also by planning a trip before end of May you can avoid masses of people that arrive for Memorial Day. What we did not plan for was the moon phase and rising. As it turned out there was no moon and overcast skies. Managing to photograph this sparrow sized owl on a pitch-black night, in a dense forest is almost impossible. We spent several hours on our first evening trying to locate this very small owl. Modifying our search, we decided to look for some of the other Yosemite owls.

Great Gray Owl – A Miss

Great Gray Owl in Yosemite Wawona Meadow

On our way into the park we had heard Great Gray Owls calling in the Wawona meadow. We headed back to this location to see what we could find. Two Great Gray Owls were calling in the forest across the meadow. WE spent about a half hour trying to entice the owls out of the forest. Finally one of the owls flew over to the tree that we were standing under. The problem was that he was about 40 feet up and there was no clear view to the owl. After another half hour of trying to get him to fly over to the next set of trees, that we had walked over to, he flew back across the meadow into the forest. At this point we decided to try another location just outside the northwest side of the park. Continue reading →

American White Pelicans Feeding Behavior

American White Pelicans preening

The American White Pelican (Pelecanus erythrorhynchos) is one of two species of pelican in North America, along with the Brown Pelican (Pelecanus occidentalis). While occasionally seen in the same locations, American White Pelicans and Brown Pelicans prefer different habitats and their manner of feeding is as different as their plumage.

Gray Jay – Perisoreus canadensis

The Gray Jay ranges from east to west across the northern boreal forests of America. “Camp robbers” are what they are popularly know as. They may even fly onto someones hand or head for food.

Description and Family

Gray Jay is unique in appearance, relative to the other crow, jay, and magpie members of the Corvidae family. Its small black bill is the most notable difference. This gives it the appearance of an over-sized chickadee.

The Gray Jay is medium size and fluffy. It is a pale gray jay with a light underside and no crest. All races have black eyes, feet, legs, and bill. In North America there are three readily distinguishable populations of Gray Jay. The photos here show the Rocky Mountain version or color pattern. Pacific birds have a darker head and brownish tinged backs. Taiga (northern) populations are grayer above and have a slight grayish belly. There are eleven races within these three color forms.

Vermilion Flycatcher

Male Vermilion Flycatcher, Mazatlan, Mexico

The Vermilion Flycatcher (Pyrocephalus rubinus) is a small tyrant flycatcher in the family, Tyrannidae. Vermilion Flycatchers live in the New World, ranging from central Argentina and covering much of South and Central America. Ornithologists recognize at least 12 sub-species of Vermilion Flycatcher. Some experts think the Galapagos Island Vermilion Flycatchers may be a full species on its own.

In the United States, we find Vermilion Flycatchers mostly in the desert southwest, where their range extends to southern Nevada. Their California range includes much of the Mojave Desert, in San Bernardino County. Additionally, it extends across most of Riverside and Imperial Counties and into Los Angeles, Orange and San Diego counties. In coastal California, we see Vermilion Flycatchers increasingly often though more likely as winter visitors. However, their range is expanding and there are indications that their breeding range is expanding towards the coast. Here in Orange County, Vermilion Flycatchers often use edge habitat like golf courses and athletic fields. Continue reading →

Magpie – Black-billed and Yellow-billed

Magpie Origin

This Black-billed Magpie was photographed in Denver Colorado. It is common to see either of the American Magpie species walking on the ground foraging for food.

The magpies of North America are very visually distinctive from other birds and thus easy to identify. Although the Black-billed Magpie is very similar in appearance to the European Magpie, it is larger and genetically unique. DNA analysis places our two magpies as separate from the European Magpie. DNA distinctions caused the AOS to divide the American Magpies from the European Magpies. The same logic should apply to the Korean subspecies. The ancestral magpies, after dispersing across Eurasia and becoming isolated in Korea, then crossed over the Bering Land Bridge into the Americas at about 3 to 4 million years ago.Strictly speaking, using DNA comparisons, the AOS (American Ornithological Society) could potentially merge our two magpie species.
