With bits of DNA extracted from century-old museum specimens, researchers have found a place for the extinct Passenger Pigeon (Ectopistes migratorius) in the family tree of pigeons and doves, identifying this unique bird’s closest living avian relatives for the first time. The new analysis, which appears this month in Molecular Phylogenetics and Evolution, reveals that the Passenger Pigeon was most closely related to other North and South American pigeons, and not to the Mourning Dove, as was previously suspected.
“This research demonstrates the remarkable potential of DNA to answer questions about species that no longer populate our planet,” says Dr. Jack Dumbacher, Curator of Ornithology at the California Academy of Sciences. “The Passenger Pigeon has been extinct for almost 100 years, but with the help of museum specimens and DNA analysis, we’re still learning new information about the bird’s evolutionary history and its place on the tree of life.”
Naturalists have long lamented that one of North America’s most spectacular birds was also one of the first to be driven to extinction by humans. In the early 1800s, the Passenger Pigeon was the most abundant bird species on the planet, even though its range was limited to the eastern and central forests of the United States and parts of eastern Canada. Flocks of Passenger Pigeons included millions of birds—they were so vast that they darkened swaths of the sky up to a mile wide.
Passenger Pigeons followed their food, settling down in forests that periodically produced a superabundance of acorns and chestnuts. The pigeons nested in dense colonies covering hundreds of acres. This made them easy targets for human predators. Intensive pigeon hunting in the mid-to-late 19th century disrupted the birds’ ability to breed. These hunting sprees, coupled with habitat destruction, rapidly drove the Passenger Pigeon to extinction. (The last of her kind, a Passenger Pigeon named Martha, died in the Cincinnati Zoo in 1914.)
To find the Passenger Pigeon’s place in the evolutionary history of pigeons and doves, Dumbacher and his colleagues compared sequences from two of its mitochondrial genes with those of 78 species of pigeons and doves from around the world. Their analysis revealed a surprising result. Most scientists had assumed that the Passenger Pigeon’s closest relative was the Mourning Dove, a smaller species that shared the Passenger Pigeon’s relatively long tail. However, the DNA comparison showed that the extinct bird’s closest living relative is the Band-Tailed Pigeon (Patagioenas fasciata), a bird that is commonly found in California.
North America’s largest pigeon, the Band-Tailed Pigeon is distinguished not only by its large size but by its distinctive coloring, with yellow legs, a patch of iridescent greenish-bronze feathers on its neck, and a yellow bill with a black tip. Despite its large size, the bird is surprisingly adept at feeding on berries and seeds in the tops of trees. In northern California, it is found in mixed evergreen forests and redwood forests.

Objective: The main objectives of the present study were to investigate the rock pigeon parasitic communities from Iraq as well as reporting on the prevalence and intensity of various infections from both sexes.
Methods: An examination of 128 specimens of the live rock pigeon Columba livia from Iraq was undertaken. The samples were obtained from several localities of Iraq. Blood samples were examined for haemoprotozoa, carcasses were investigated for the ectoparasites throughout their body skins and feathers, and the alimentary canal was examined for protozoans and helminths.
Results: Twenty-seven species of parasites were identified. They comprised 1 Fungi, Candida sp.; 4 Protozoa, Eimeria labbeana, Trichomonas gallinae, Haemoproteus columbae and Plasmodium sp.; 8 Cestoda, 4 of each of the genera Cotugnia and Raillietina; 4 Nematoda, Ascaridia columbae, A. galli, Capillaria obsignata and Synhimantus spiralis; and 10 Arthropoda, the commonest of which were the wing and tail feather louse Columbicola sp. and the pigeon louse fly Pseudolinchia canariensis. Infection indices are provided for each species and in respect to both sexes of the host.
Conclusion: The issue of zoonosis is raised, so is the role of the rock pigeons in acting as a reservoir and spreading some of the disease agents associated with other avian populations including poultry. Seven of the species are newly introduced to the parasitological list of Iraq and for this country the rock pigeon is a new host record for another 9 of the endoparasites that were diagnosed.

The number of passenger pigeons went from billions to zero in mere decades, in contrast to conventional wisdom that enormous population size provides a buffer against extinction. Our understanding of the passenger pigeon’s extinction, however, has been limited by a lack of knowledge of its long-term population history. Here we use both genomic and ecological analyses to show that the passenger pigeon was not always super abundant, but experienced dramatic population fluctuations, which could increase its vulnerability to human exploitation. Our study demonstrates that high-throughput–based ancient DNA analyses combined with ecological niche modeling can provide evidence allowing us to assess factors that led to the surprisingly rapid demise of the passenger pigeon.
To assess the role of human disturbances in species’ extinction requires an understanding of the species population history before human impact. The passenger pigeon was once the most abundant bird in the world, with a population size estimated at 3–5 billion in the 1800s; its abrupt extinction in 1914 raises the question of how such an abundant bird could have been driven to extinction in mere decades. Although human exploitation is often blamed, the role of natural population dynamics in the passenger pigeon’s extinction remains unexplored. Applying high-throughput sequencing technologies to obtain sequences from most of the genome, we calculated that the passenger pigeon’s effective population size throughout the last million years was persistently about 1/10,000 of the 1800’s estimated number of individuals, a ratio 1,000-times lower than typically found. This result suggests that the passenger pigeon was not always super abundant but experienced dramatic population fluctuations, resembling those of an “outbreak” species. Ecological niche models supported inference of drastic changes in the extent of its breeding range over the last glacial–interglacial cycle. An estimate of acorn-based carrying capacity during the past 21,000 y showed great year-to-year variations. Based on our results, we hypothesize that ecological conditions that dramatically reduced population size under natural conditions could have interacted with human exploitation in causing the passenger pigeon’s rapid demise. Our study illustrates that even species as abundant as the passenger pigeon can be vulnerable to human threats if they are subject to dramatic population fluctuations, and provides a new perspective on the greatest human-caused extinction in recorded history.

The Red-billed Pigeon, Patagioenas flavirostris , is a relatively large pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the Pale-vented Pigeon.
The Red-billed pigeon is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
The Red-billed Pigeon, Patagioenas flavirostris (see Johnson et al. 2001), is a relatively large pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the Pale-vented Pigeon. It is found in open country with some trees, large clearings and cultivation in lowlands and middle altitudes to 2100 meters.
The Red-billed Pigeon has a large range, estimated globally at 830,000 square kilometers. Native to the United States and Mexico as well as Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua, this bird prefers neritic, oceanic, and coastal marine ecosystems. The global population of this bird is estimated at 500,000 to 5,000,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List.

The feral pigeon (Columba livia) carries with it a reputation that runs counter to conservation: it is feral, exotic and invasive and even considered down right filthy. But upon closer inspection, the pigeon could be a subject worthy of study for both ecological and social science purposes and highlight the importance of urban species in ecology. This insight on pigeons occurred during an urban ecology study that focused on habitat and population dynamics of the birds and is also supported through an extensive literature review. As a nearly ubiquitous species, we discuss how important pigeons are as a prey-base for numerous raptors and underscore our position by highlighting several studies on the biological uptake of environmental contaminants that may have benefited from including the pigeon as part of the research. We further our stance on the importance of pigeons in urban ecology by highlighting additional concerns such as zoonotic disease and climate change. We expand our case by turning to the social construction of nature, the importance of public participation in conservation. Once again, the ubiquitous presence of pigeons lends itself well to citizen science in ecology and conservation, especially to show trends across a range of geographic locations. In short, this commentary strives to reconceptualize the feral pigeon, promoting the bird as a valuable asset to ecological and social research in ways that raise awareness for conservation concerns and advance our scientific thinking.

If it makes you feel any better, humans aren’t the only animals that forget things. Researchers have found that homing pigeons do the same. The new findings, they add, suggest an underlying continuity across the human and animal world in how the brain works.
The knack of remembering and forgetting is the brain’s way of filtering information to manage its limited storage capacity. For example, you briefly store information about trees and cars around you in your working memory, but if someone tells you to focus on a speeding truck, your brain uses a process called executive control to remember that object longer. Meanwhile, you forget the others. In humans, this filtering is performed by the prefrontal cortex.
To test whether the avian brain has a similar filtering mechanism, Michael Colombo, a neuroscientist at the University of Otago, New Zealand, and colleagues subjected homing pigeons to a memory test. First, the researchers trained the birds to know that a high tone means they should remember an object, while a low tone means they can forget it. They then showed the birds one of two shapes (circles or dots) or colors (blue and green). After a bird pecked three times at the image, the researchers sounded a tone. Birds that heard the remember cue fired up neurons in a region of their brain analogous to the human prefrontal cortex (as measured via implanted electrodes), Colombo’s team reports today in PLos Biology. And those birds did, in fact, remember the objects: 79% of the time, they correctly pecked at the original object again when shown multiple images 3 seconds later. In contrast, birds that heard the forget cue did not exhibit sustained activation of the same brain area, and only in about 44% of cases did the birds correctly identify the original object. Thus, the researchers argue the birds use a similar mechanism as humans to filter their memories.
