![]() The image above and the four below come from the same spot, the row of palm trees along the creek at Agua Caliente Park in Tucson. Immediately above and below are either one or both of the parents of the fledgling shown in the next two pictures down. The adult(s) were photographed while watching over the downy young bird from the row of palms. The nestlings shown at the bottom of the page were photographed on a nest in the same area a year earlier. |

![]() This young bird had first flown within the last three days when the pictures above and below were taken in 2010, showing it in a mesquite a few yards from the row of palm trees where the nest was, and from which the adults were watching. The bird looks to be about equally downy as the young birds still in the nest in 2009, shown further below, probably because the 2010 nestling had fallen out of the nest before it could fly. Park rangers supplied a box for it, and the parents continued to feed it until it fledged. |

![]() The adult female is on the left, above, with the three young birds on the right. They are out of the nest, so no longer nestlings, but still spending their time in the nest tree or neighboring trees, so "branchlings" rather than fledglings. The young of large tree-bred raptors pass through this intermediate stage before they are able to forage on their own and hence fully fledged. These Great Horned Owls were nesting near where I live, in Santa Clara County, California. The branchlings are shown with one of them stretching one wing and the tail, below. | |
