20026  Other Nature Related Information / General Nature Discussion / CALIFORNIA CONDORS A3 AND 89 FEATURED IN NEW DOCUMENTARY FILM SERIES on: 31-Jul-10, 06:39:28 AM


Gymnogyps californianus

I just completed working on a project with Nova Productions Média, from Québec (www.humanima.com). Nova Productions is producing a documentary film series titled “Humanima” on three specific birds that occur in Utah: white-faced ibis, American white pelican and California condor.

We filmed California condors A3 and 89 at Lava Point on the Kolob Plateau near Zion National Park in southwestern Utah. You could see the wing markers placed on the soaring condors, as they kited on the wind and rising thermal currents. California condor with wing marker A3 (343) is a female hatched May 13, 2004, in captivity at The Peregrine Fund’s World Center for Birds of Prey in Boise. She was released at the Vermilion Cliffs in northern Arizona on Oct. 12, 2005. The other condor with wing marker 89 (389) is a male that was wild hatched on May 5, 2005, in the Vermilion Cliffs. He fledged on Nov. 30, 2005. His parents are California Condors 114 Male and 126 Female, residents of the Vermilion Cliffs in northern Arizona.

During the 50 years I have studied birds, I have seen ample evidence of a complex web connecting the ecosystem. There is a grand scheme at play. Some birds are pollinators, others insectivores; others cache nuts and other foods that when not recovered will grow into trees, shrubs and various other plants. Then there is the sanitation engineer, the California condor.

It is the largest flying bird in North America and is one of the most endangered birds in the world. The 109-inch wingspan makes it a superb glider. The condor rarely flaps its wings, except during takeoff and landing. This gliding ability conserves energy and enables it to cover great distances every day as it searches for carrion.

Since it is a carrion eater, its orange head is featherless. This prevents fouling feathers with bacteria as it puts its head into the carcass of an animal. These are enormous birds weighing between 15 and 22 pounds. Its feathers are predominantly black. You can see white wing linings as condors soar the skies of southern Utah.

The last nine remaining wild condors were captured in 1987. A captive breeding program at the San Diego Zoo and the World Center for the Birds of Prey in Boise has been successful in producing young. Several California condors have been reintroduced into California and the Red Cliffs of northern, Arizona. Several of the Arizona condors have moved north to more of their historical range in Utah. They now patrol the skies over Zion National Park and the Kolob Plateau in southern Utah.

Condors do not begin breeding until they have reached breeding age, 6-8 years. California condors released in Arizona have begun breeding and wild hatched condors have been produced. A California condor lays only one egg in a clutch. The young is dependent upon the parents for more than one year, and consequently condor pairs usually breed every other year.

Because they are scavengers, condors tend to be highly curious. They are attracted to human activity and tend to perch on power lines. These hazardous activities have resulted in the electrocution of several released birds and the poisoning of others (antifreeze ingestion and lead poisoning from hunter-killed deer and elk). Utah Wildlife In Need (www.UWIN.org) is funding a copper bullet to give hunters in the field in this area so they can enjoy their sport without the unintended consequences of lead bullets. California condors have been recaptured and re-released in more remote areas, and now all condors scheduled for release are given “aversion training.” The birds are provided with a choice of perches: natural snags and mock power poles. When they land on the power poles they are given a mild shock. They are also subjected to a series of human aversion exercises.

The California condor normally dominates other scavengers and usually does not hesitate to take a carcass away from smaller species. The exception is when a golden eagle is present. Although the condor weighs about twice as much as an eagle, the superior talons of the eagle command respect.

…30 days hath September, April, June and…yikes, the last day of July.

Faithful blog people noted a “crow/raven/blackbird” poked a hole into the third egg whilst I was away. The orb itself still has fine form. I cannot think that any contents were palatable. As noted yesterday, we have had a good number of jays about and still do this morn, it may have even been one of them. Many odes to the orb have been written.

Two larger fish were brought to the “table” yesterday; a huge perch and a blue trout. I have spoken in the centre of noting that once the juvies were able to fly, the the size of the fish seemed to be smaller than earlier on in the breeding season, thinking that the the parents were choosing to catch smaller fish for the inexperienced young to eat. As the juveniles continue to mature we shall see if this is in fact a change in the adult behaviour. Yesterday, both of the youngsters ate on the nest and flew off with their heavy partially eaten prey. One, found that the fish was a wee bit too heavy to comfortably fly. It returned with it a few moments later. Once more had been eaten it flew off with a lighter load. This is much like an adult would do when fish are caught too heavy to lift and fly just above the surface of the water and eat at the waters’ edge before flying off to a safer perch. Of course the juvies will soon be flying with fish and need to have the skills to do so.

If we have many visitors today I may not be able to respond as frequently as I would like. I will do so as soon as I am able.

Have a wondrous day on your own patch as well as this one! Rinchen

20030  Other Nature Related Information / General Nature Discussion / Peregrine falcon killed by discarded rubbish (Scotland) on: 30-Jul-10, 09:06:35 PM
A young peregrine falcon has had to be put down after losing its feet due to rubbish discarded on a south west Scotland shoreline.

The Scottish SPCA was called out to cliffs between Leswalt and Portpatrick to recover the bird last week.

It had become tangled in nylon string in its nest which resulted in both its feet being amputated.

The SSPCA has urged people not to dump rubbish on beaches or in the water to avoid harming such "magnificent" birds.

Officers were called to the cliffs in Dumfries and Galloway on 23 July after a concerned member of the public saw the bird of prey struggling to leave its nest.

One inspector descended the cliff face to release the bird from the snagging.

However, both of its feet had been amputated after its legs had become snared in plastic wire and netting which the parents had used to build the nest.

Due to the extent of its injuries the SSPCA decided the only humane option was to put the falcon to sleep.

Insp Janet Proudlock said: "This was a very sad outcome for everyone involved in the rescue, including the gentleman who contacted us after he had been watching the peregrines rear their young for several weeks.

"I directed our rescue team from sea level and we were able to quickly reach the bird and release it from the plastic and twine that was preventing it from leaving the nest.

"We were all desperately sad, but at the same time, glad to have been able to relieve the bird from the nest as it would otherwise have slowly starved to death."
'Sad fact'

Two other chicks which were in the same nest have successfully fledged.

Insp Proudlock said it was a "sad fact" that rubbish was now a feature of countryside and coastlines and birds often built their nests from such materials.

"The birds don't know the difference between nylon string and grasses and this is the reason why tragedies like this occur," she said.

"If people just cleaned up after themselves we wouldn't have to deal with this sort of issue.

"To lose a magnificent bird such as a peregrine falcon is very sad indeed.

(I didn't know Falcons built nests)
  ??? This is really a sad story. Poor baby.

I watched it all the time after school, until it ended. No one I know remembers this. Someone out there must have seen it.

Thankfully, I missed it !!!

Warm and greyish this morn. Rain is forcast for later today.

The current questions are; “where is the female?”, “who caught the fish?” and “who is eating most of the fish?”

The answers lie in very careful and accurate, verifiable observation. I will  place here some personal comments. “Our” female is spending more time away from the nest; a gradual weaning of  the breeding season. This will continue to occur until one day (probably soon) she will wend her way south, having completed another fantastic episode of her life. And yes, she appears strong and is well able to look after her own needs. Perhaps a juvie caught a fish yesterday. As we have observed over the past fortnight the male deliveries to the nest are nearly instantaneous. We have also observed that the chicks are able to fly with objects (pine cones, sticks, and fish) and know that they are able to land in the loch and alight from it. They are also able to perch and even eat fish away from the nest, albeit it is surely easier to eat on the “table”. It is possible that there was a fish exchange away from the nest. Our views from the camera and hides are remeber very limited, selective and comprehensive. About an hour after the perch came in, another fish was delivered by “our” male. Both of the adults have made consecutive food drops in the past. Of course we have very talented and accompished osprey here. As someone who has recorded plenty of natural history and biometric data I suggest that further observation is required. The juvies will both be too soon, to many, fending for themselves. Both of the young are healthy, active and progressing at their own pace. As I noted yesterday in a response to a comment, I indicated that the siblings have been getting along famously since hatch date. Competion is healthy. Each individual has its’ own needs.

Let us experience and enjoy the activity provided by natural world. Rinchen

Is it unusual for the falcons to go back to the nest box after all the rearing and fledging is complete? I don't think I can remember a season when this was as common as it appears to be this year... maybe I was not paying attention!

Slainte!

Bobbie, they are bonding, MK definitely did this too. Just showing their  heart for each other. (my way of putting it). They bow to each other.
