Brown Shrike from Asia visits California...and sightings of other animals.

A Brown Shrike,  Lanius cristatus is a Eurasian bird species; it is extremely rare for individuals to stray to North America. Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey.

Several populations form distinctive subspecies which breed in temperate Eurasia and migrate to their usual winter quarters in tropical Asia.  This bird was visiting a coastal band of freshwater ponds with grasses, cattails and willow.

This is the third record in California, with a handful of other North American records in Alaska and one in Nova Scotia.  The bird had been there for weeks and Gary Lindquist and Jeff Marszal were quick to spot the bird the day I arrived on Clam Beach, McKinleyville, California.

The bird is much more difficult to observe on cool, cloudy or wet days and we witnessed a correlation of activity with sunshine, as the bird sallied for suddenly active insects.  Gary mentioned he believed frogs may be taken also and many were calling in the coastal freshwater ponds.




The bird frequents this shrubby vegetation.

The middle bird was at Salton Sea in SW California in late 2010- early 2011. I was able to get to the inland sea due to snow delays in the east that gave me an unexpected day in S Cal.  This subspecies may be split into a separate species from other forms that have been seen in Alaska in the past.



Coast Redwood - The Global King of Biodiversity

The Coast Redwood is the tallest species on earth, forming forest stands of unsurpassed biomass.  Sequoia sempervens (ever living), was probably named in honor of the Cherokee leader Sequoyah of Tennessee.  It reaches 379 feet with a base diameter of 22 feet and can live to 2,000 years.


The largest individual tree was discovered only in 2006 during a survey of a remote section of Redwood National Park in NW California.  Below there is a video of the record tree being measured.




I met with Jeff Marszal, a Resource Management Specialist to plan upcoming NBP projects and we were able to visit this incredible park.  He had told me about the difficult forest survey conditions, with steep slopes, dark conditions, wet understrory and fallen logs 20 feet high and 200 feet long.  It was time consuming, but worth it to hike through this Biosphere Preserve with the sky blocked out by massive tree after tree.



This is an ancient community, dominated by taxa and biodiversity from the Age of Dinosaurs, such as mosses, ferns, conifers, spiders, fish and amphibians.  Warm air from the land passes over the inshore waters forming fog that precipitates out on the vegetation like it once did in most of North America when moist, redwood like forests were dominated by giant reptiles.

The Roosevelt or Olympic Elk prefers open areas but also seeks out forests.  This is the largest of the four remaining subspecies of elk.  

The forest is too dark to get a clear panaromic view even with flash equipment.



Same tree as above but the flash was moved closer. 






The Coast Redwoods range along a narrow strip of habitat along the NW coast of North America.  They provide a home for many species including the puffin-like Marbled Murrelet whose habit of nesting in trees was suspected but not documented until a tree-climber found a chick in 1974.  It was one of the last North American bird species to have its nest described. The Marbled Murrelet has experienced declines due to logging and any significant climate change could impact many species including the Coast Redwood. 

That is a pair of lime green binoculars on the trunk of this Coast Redwood that was over 20 feet in diameter.

What!? A Highway Through the Serengeti?

A controversial road that would cut across one of the most spectacular ecosystems and global biodiversity depositories, the Serengeti Plains in Tanzania, may soon receive approval. 

A sample letter for your use is at the end of this article.

If the road is completed in its planned location it would connect western, inland areas, with coastal ports and bisect thousands of acres of pristine African savanna. It would slice directly through the traditional migration route of more than 2 million wildebeest, zebra, gazelles, giraffes, elephants and the cheetahs, leopards and lions that depend on it. 

The Mara River snakes through the Serengeti Plain.
These inland areas possess deposits of rare earth metals which are in short supply and are needed for various items like cell phones.  China recently announced it would decrease export flow of these metals to supply its own growing industries and this may be an already successful attempt to drive up metal prices.


The Serengeti is a critical feeding and calving area for millions of grazing mammals.  In turn the vegetation and herbivores directly or indirectly support thousands of other species of animals. 

A highway will subject many species to roadkill pressure, poaching, disruption of the migration and the inevitable supporting development, such as gas stations, food marts, souvenir shops, residential space, etc.

Ruppell's Vultures feed on a road killed gazelle.  And this was a low speed, dirt road. 
 
Servals are a medium sized species of cat which we saw in areas with higher grass..  The Cheetah speciated from an ancient line of Servals. 
Tanzania is a poor country but there is an alternate route (see link, below).  Tanzania has had an excellent environmental stewardship record; so these plans are a bit shocking.  On our visit we saw Chinese government officials inspecting road improvement projects. 

The connection between manufacturers' urgent need for rare earth metals, China's recent announcement to reduce metal exports and their active investment in roads in Tanzania makes me realize what has occurred to produce this destructive plan.

Since we all contribute to the world demand for metals we should try and mitigate our impacts, SO:  

Please call, email and/or write the Tanzanian embassy and advise them you are vehemently opposed to a highway through the world's greatest biological masterpiece.  At the end of this article is a base letter for your customizable use.   Email finished letter to

We went on a biodiversity study in this exact area and it is beyond comparison.  Here is a small part of what we saw.

The migratory mammals follow a circannular route that coincides with the rain patterns that influence grass growth on this high plain.  It can be surprisingly cool at times.

When walking an armed guard is best due to the remote possibility of an animal attack.
This male took down a Wildebeest and soon started to call for a female that eventually arrived.

The female came in.

This Cheetah was still wet from the early morning dew of the plains when we were lucky enough to spot it.  They often hunt at day break when the Lions are often satiated from their night kills.  This cat ignored us, and ate quickly while nervously looking in all directions for Lions or cleptoparasites that would easily kill it or steal its prey. 
Here's the whole scene.

African Fish Eagles (Haliaeetus vocifer) are in the same genus as our Bald Eagle. Haliaeetus means lover of fish.  Bald Eagles are increasingly seen on the Rahway River, NJ especially in migration.  A female Fish Eagle can be 8 lbs, with a wingspan of 8 feet.  We saw a handful of these eagles.

We had this Crowned Crane on the east plains not far from the Ngorongoro Crater.

In places where they are not harassed or hunted by people you can get very close to Giraffes.  There are many subspecies but the only other species in the family is the rarer Okapi which was confirmed to be more than a wild rumor finally in 1901. 

This Hippopotamus has horizontal "bath tub" lines caused by moving from one small pool to another.  Several species of birds like these jacanas have a symbiotic relationship with semi-aquatic animals. 

Lilac-breasted Rollers need at least a few trees to ambush their prey of insects and small animals. 
White-crowned Shrikes are loud, usually in groups and perch in thornbush or acacias.

African Elephants are dwarfed in the vista.  They are part of the complex ecological balance that suppresses the savanna from succeeding to forest.  Note the elephant damaged tree.

This is a superb starling.....yes a Superb Starling.
This Red-and-yellow Barbet stood its ground.

Re:
SERENGETI NATIONAL PARK HIGHWAY
PROPOSAL

Dear Honorable Representative of the United Republic of Tanzania:

For decades we have witnessed poorly-conceived development projects that exacerbate urban sprawl, and foster decline of rural and natural landscapes.   In the short term these projects sometimes looked advantageous but in the long term they were not good for the area or the people.

Highways through protected parks, forests and natural areas slowly destroy long-term ecosystem function. Remnant ecosystems severed by such poorly conceived projects eventually degrade and fail to support the wildlife they are intended to protect.

Serengeti National Park is a worldwide natural gem, and should not be sacrificed for the insatiable resource extraction needs of our human society. If the true, long-term costs of the destructive impact to Serengeti National Park and the future of both nature and humankind were to be factored into the cost of extracting the rare metals, the project would prove to be unwarranted.

Please do not allow your wonderful nation of Tanzania to succumb to the greed of the material world, and sacrifice one of the world’s greatest treasures that you have stewarded so wonderfully, in the face of overwhelming odds, for so long.

Thank you for your consideration.

Sincerely,
