After the key moment it appeared as though the female dismounted from the female superior position. The conclusion appears to be quite brutal for the male Ozone Warbler. (That's gotta hurt!)

I am very curious about the decoy method of attracting the Ozone Warbler. However, the video link is not productive. ? ? ? All I get is a blank page. :eh:

RickMasters wrote:Decoys used to attract Ozone Warblers

Ornithologists, weary of climbing trees to study Ozone Warblers in their native habitat, have developed a new method - the use of decoys to attract the strange birds.

In this video, an Ozone Warbler with a captive female appears to be attempting to nest near the decoys, perhaps in the hope of laying an egg.

Ornithologists determine reason behind low egg count of Ozone Warblers

South American ornithologists have cleverly mounted tiny video cameras to Ozone Warblers and their captive females on mating flights.

The mystery of low or zero reproduction in Ozone Warblers is now revealed to be due to the rejection of the male by the captive female. In video after video, researchers have found that the female is extremely dissatisfied - even distressed - with the limp wings and slow response presented by the Ozone Warbler and may indeed prefer the rigid members, speed and protection evidenced by more robust avian species.

Ornithologists examine an Ozone Warbler found nesting in a shallow crater, clutching an egg. Unfortunately, the egg was cracked and did not produce a chick. Crater nesting behavior is not as common as tree nesting, and more Ozone Warblers have been found dead in craters than in trees, leading ornithologists to suspect physical or mental defects as causal.

Instincts of the Ozone Warbler
Charles Darwin’s Natural Selection
Mental Powers and Instincts of Animals
Page 523
Wonderful & admirable as most instincts are, yet they cannot be considered as absolutely perfect; there is a constant struggle going on throughout nature between the instinct of the one to escape & of the other to secure its prey. If the instinct of the Spider be admirable, that of the Fly which rushes into the toils is so far inferior. Rare & occasional sources of dangers are not avoided; if death inevitably ensues & caution cannot be learnt by seeing others suffer, it seems that no guardian instinct is acquired; thus the ground within a solfatara in Java is strewed with the carcasses of tigers, birds & masses of insects killed by the noxious exhalation, with their flesh, hairs & feathers preserved, but their bones entirely corroded. The migratory instinct not rarely fails & animals, as we have seen, are lost. What ought we to think of that strong impulse which leads Lemmings, Squirrels, ermines & many other animals, which are not regularly migratory, occasionally to congregate & pursue a headlong course, across great rivers, lakes & even into the sea, where vast numbers perish; ultimately it would appear that all /109/ perish. The country being overstocked seems to cause the original impulse; but it is doubtful, whether in all cases scarcity actually prevails. The whole case is quite inexplicable. Does the same feeling act on these animals, which causes men to congregate under distress & fear; & are these occasional migrations or rather emigrations a forlorn hope to find a new & better land? The occasional emigrations of insects of many kinds, associated together, which, as I have witnessed, must perish by countless myriads in the sea, are still more remarkable, as they belong to families none of which are naturally social or ever migrate.
The social instinct is indispensable to some animals, useful to still more for the readier notice of danger, & apparently only pleasant to some few animals. But one cannot avoid thinking that this instinct is carried in some cases to an injurious excess . . .

In this rare footage, Italian ornithologists have captured an Ozone Warbler and attached a small video camera to its head to study the expected nesting behavior. The video begins as the Ozone Warbler is released in hopes that it will follow another Ozone Warbler on a mating flight of some distance, but for some reason it chooses to immediately make a nest before mating. Ornithologists speculate that the light rain may have played a role in this decision because Ozone Warblers have been previously observed to fall out of the sky in rain due to a flaw in their evolutionary design - and this Ozone Warbler appears to realize that flying in the rain may not be a good idea and therefore immediately descends to make a nest. At the end of the video, ornithologists can be seen climbing a ladder to the nest to see if the Ozone Warbler had laid an egg. Unfortunately, no egg could be found. The ornithologists, now convinced that the Ozone Warbler, calling piteously and unable to reproduce or even sustain itself in its nest, is most likely an evolutionary dead-end and had the unfortunate creature stuffed and placed between a Dodo and Great Auk in the Italian Museum of Natural History in Rome.
