Giovanna ha scritto:Rileggendo il precedente post di Donna Daniel e riflettendo sull'inquietudine manifestata dalla coppia, sulla loro evidente confusione di fronte all'evento atteso, la schiusa, che non avveniva, credo di poter dire: si, è un intervento giustificato, anche se, in un primo momento, shocking. Speriamo che riprendano gli amori, come previsto, e che anche per loro ci siano presto nel nido i piumini bianchi da accudire che costituiscono il senso profondo della loro vita in questa stagione.
Proprio per Scout, in modo particolare, sono i miei auguri per la festa della mamma.
E per tutte le mamme falco di tutto il mondo

Da un punto di vista umano, ho le stesse perplessita', lasciare ai 2 le loro (forse inutili) uova, ma da un punto di vista "falchesco" mi rendo conto che i 2 avrebbero covato ancora un bel po' prima di decidere di abbandonare le uova, l'obiettivo dei falchi e' mandare avanti i loro geni ma aspettare per altre settimane metterebbe a rischio i pulli di un'eventuale seconda cova... estremamente auspicabile e alquanto probabile... ma solo se tra non molto.. : ci vorranno un paio di settimane per deporre altre uova se questo sara' il caso... poi a seconda del loro numero una settimana per deporle tutte, per la schiusa una quarantina giorni e altrettanti per portare i piccoli all'involo (scusate se non ricordo esattamente, dovrebbero essere alcuni giorni in piu' per la seconda delle due fasi...) quindi minimo un paio di mesi per renderli autonomi nella alimentazione... siamo a meta' maggio... ogni giorno perso inutilmente e' un rischio maggiore per i prossimi...
Allora, nonostante in questo caso sarei piu' per lasciar fare alla natura senza "spingerla", per il bene dei possibili nuovi pulli accetto questa soluzione.

Da un post di oggi di Rita Woods:
"It can take up to 2 weeks for a falcon pair to re-nest (lay a 2nd clutch of eggs), so we can still keep hoping!"
Dato che è sicuramente un'autorità in materia e si occupa di rehab con esperienza e dedizione, speriamo anche noi.

UPDATE FROM DONNA DANIEL:

FRIDAY, MAY 18, 2007

SUPRISE VISITORS
After being absent from the nest ledge a few days, the falcons (especially Scout) are making an appearance again. But first, on Wednesday two pigeons were seen on the ledge!!! Make that very BRAVE pigeons! Obviously, the peregrines were away from the immediate area for a brief time that the pigeons could stop by safely, otherwise they likely could have been lunch!

Since Wednesday, Scout has been checking in and even working on the scrape. Today she perched on the nestbox camera housing for about an hour. This is a good sign in that it would indicate that she is still interested in the nest box on the Rhodes Tower (vs. moving to a new site within the downtown area). But does it mean there will be a 2nd clutch? Not necessarily. Scraping is part of the territorial process--in fact, after young have fledged from the nest successfully the adults will go back into the nest box in late summer and scrape in the gravel when we know they have no intention of nesting again until the next season. It is definitely a good sign that Scout is scraping now, but it is not guaranteed we'll see more eggs this year. We'll just have to wait until we see eggs (or not) to know for sure...! As for the eggs from the first clutch, I hope to be able to find out next week if they were fertile. I will post the information as soon as I know.

Orville e Scout sono ora insieme nel nido apparentemente intenti ai preparativi che in genere preludono alla deposizione delle uova. Speriamo bene

Note from Donna
Unhatched Egg Report
The 3 eggs that were recovered from the nest on May 11, 2007, have been determined to be infertile. Since Orville has a history of successful breeding, it is likely due to Scout's young age. It is normal that some or all of the eggs may not be fertile on a first-time nesting attempt if the bird is not fully mature.

Some have wondered why we would take the eggs from the nest vs. letting "nature take its course." As stewards of the peregrine falcon population in Ohio, it is the Ohio Division of Wildlife's responsibility to foster these birds and protect them. Part of protection includes monitoring their reproductive success. It would be irresponsible of us not to evaluate the eggs to determine why they did not hatch. Back in the era of DDT, had wildlife managers not evaluated reproductive success (or lack thereof) of peregrines and other birds of prey the threats that chemical contamination posed to the species survival may not have been discovered. While DDT is less of a concern now, other contaminants may not be. So, as part of our peregrine falcon management program we note when nests succeed as well as when they do not and try to determine the cause of failure. This information is evaluated and used to track the species' progress over time.

On another note: along with Scout, Orville has been seen more frequently over the past few days. One or both birds seem to be checking out the nest box several times a day.

Le uova non erano fertili. Mi sembra che l'intervento potrebbe risultare molto utile. In ogni caso queste spiegazioni sono chiare e l'orientamento espresso da Donna Daniel estremamente preciso e deciso.

Bè, ci consoliamo, niente sparizioni, per i piccoli, sarà per il prossimo anno.
Ma almeno sono insieme!

Another Successful Year For Ohio’s Peregrine Falcons

COLUMBUS, OH (08/01/07; 1439)(readMedia)-- COLUMBUS, OH – Biologists with the Ohio Department of Natural Resources (ODNR) Division of Wildlife estimate 56 young peregrine falcons fledged from 19 successful nests across the state this year. In 2006, a record 60 peregrine falcon chicks fledged from 18 nests.

“We had a record-high number of successful nests this year,” said Dave Scott, peregrine falcon project coordinator for the ODNR Division of Wildlife. “However, eggs at some nests did not hatch and this reduced our total production compared to last year.”

In all, 23 territorial pairs of peregrine falcons were monitored around Ohio in 2007. Eggs were produced at 22 sites during 24 nesting attempts, with two pairs “recycling” and producing a second nest after initial failures.

Six falcon pairs in Cleveland, along with two pairs in Toledo and individual pairs in Aberdeen (Brown County), Akron, Canton, Cincinnati, the village of Cleves (Hamilton County), Dayton, Eastlake, Ironton, Lima, and Youngstown produced between one and four young per nest. Nests located in Columbus, Lakewood and Springfield failed this season. A pair reported in Lorain did not nest this year.

A new nest was identified late in the 2007 season near Oregon in Lucas County, bringing the total of known territorial pairs of falcons in Ohio to 23.

“After the nesting season and prior to migration, Ohio’s peregrine falcon population is estimated to reach 100 to 120 birds,” Scott added. Included in that number are individual falcons that have been spotted in other areas of the state. These birds, as well as the territorial pairs that did not nest this season, could return next year to establish territories and perhaps successful nests. Migratory movements will start in late summer and early fall. Ohio’s birds probably spend their winters in the southern United States and Central America.

Anyone interested in following peregrine falcon activity in Ohio can view the latest updates online at ohiodnr.com/wildlife. The peregrine falcon page features information on the bird’s history, nest status, and links to cameras that record activity at several of the nest locations across Ohio. In 1989, wildlife experts with ODNR began reintroducing peregrine falcons into Ohio. For more than a decade, peregrines have successfully nested in Akron, Cincinnati, Cleveland, Columbus, Dayton and Toledo.

Ohio’s peregrine falcon management program is funded by donations to the Endangered Species and Wildlife Diversity Fund and sales of the cardinal license plate. Donations may be made to the Division of Wildlife, 2045 Morse Road, G-1, Columbus, OH 43229-6693, or by marking the check-off contribution box on the Ohio Income Tax form. Cardinal plates can be purchased at a local deputy registrar or by calling 1-800-PLATES-3.

Additional funding is provided, in part, through matching funds from the United States Fish & Wildlife Service State Wildlife Grants Program that benefits species of greatest conservation. (posted by Sophie on the Cleveland message board)

Un breve aggiornamento su VICTORY e VELOCITY.
Speriamo bene!
Orville e Scout sono rimasti nel loro territorio; la coppia appare unita ed è stata vista molto spesso nel nido.
Prossimamente la web cam dovrebbe essere in streaming con audio.

Donna Daniel reports on 11/07/2007.

VICTORY, is still finishing up her molt, so her pre-release conditioning is still on hold. We are optimistic that she will regain complete flight and be able to be released prior to the next nesting season. VELOCITY is being trained by a falconer to hunt, however a setback occured recently when she was attacked by a wild red-tailed hawk while in the field with her trainer. She has several puncture wounds from the red-tail's talons that are being treated. Hopefully, she will heal quickly and be back in training real soon.

Detto questo, è ora di passare alla stagione 2008.
