Een ander mannetje in beeld, Flyboy is gevlogen en Matrix zit op de richel,
waar is Durand nu?
► Jammer dat het zo vervelend is afgelopen hier, nu maar hopen dat we volgend jaar wel van mooie kuukjes kunnen genieten.

New Update from Donna... Durand has not shown any inclination to incubate the eggs since the beginning of this week, therefore, it is pretty safe to say we have a failed first-time nesting attempt. The male has not been observed via the cameras so it is unclear whether he is still in the territory or not. His presence--or lack thereof--is actually irrelevant, as even without him she should have continued incubating to term. Her change in behavior is almost surely related to subsiding hormone levels which dictate the behavior to incubate. Because the eggs were not incubated the full time required, had there been any development the eggs would have perished some time ago. In the near future the eggs will be removed from the nest with the intention of determining if they were fertile or not. As soon as that information is known I will post it here. Meanwhile, Durand continues to make appearances at the nest ledge spending time perched on the nestbox camera housing or the ledge. It is not likely that she will attempt another clutch this year--but then again anything is possible! It is unfortunate that this year's nest did not work out like many had hoped but nonetheless it is still interesting to watch what transpires and learn a little more about the species each season. (geen vertaling deze keer, heb het idee dat ik de enige ben die het leest:-) Mocht er behoefte aan een vertaling bestaan: dan lees ik het wel en doe het alsnog) |

Laatste bericht van Donna: 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 that protection includes monitoring their reproduction. We note when nests succeed as well as when they do not. Given a failure, the responsible thing to do is to evaluate the eggs to determine why they did not hatch. Productivity information such as this is compiled throughout the Midwest and is used to track the species' progress over time throughout the region. I had an unexpected opening occur in my schedule this morning so I took advantage of it to go ahead and remove the eggs from the nestbox. None of the 5 eggs were fertile. It is probably good then that Durand gave up early vs. sitting on them past the expected hatch date. This way she can get on with simply being a falcon and defending the territory when/if need be. We will hope for a better outcome in 2012! There was no sign of either falcon while I was downtown today. As usual, we'll keep the cameras up throughout the summer to help monitor the presence of Durand, the male, and any other falcon(s) that may make an appearance. This is the last of the regular nesting season updates however, if/when anything notable occurs I will post it here. Thanks everybody, for your continued support and interest in the ODNR, Division of Wildlife's Columbus FalconCam! |

Arme Durand, na al haar harde werk bleek alles gewoon voor niks te zijn.... Gelukkig is ze er zelf op tijd mee gestopt |

Zou het er dit jaar dan toch nog van komen?  Is dan wel een klein wondertje. |

Dit jaar nog? Nou, laten ze de band maar lekker verstevigen en bijelkaar blijven dan geeft dat voor volgend jaar wel veel meer kans op een mooi nest met jongen. Maar is het Durand en Matrix of is het weer een andere man? Flyboy was gevlogen. |
