Band-tailed pigeon (Patagioenas fasciata)
The band-tailed pigeon is the closest living relative of the extinct passenger pigeon. Scientists hope that learning about the band-tailed pigeon will help with the great passenger pigeon comeback! Read more about band-tailed pigeons in Audubon Field Guide.

Chromosome-length genome assembly
Download the NIATT_ARIZONA_HiC.fasta.gz file containing the chromosome-length assembly of the band-tailed pigeon genome. All modifications with respect to the draft (see below) are annotated in the NIATT_ARIZONA_HiC.assembly file. Some basic stats associated with the new reference, NIATT_ARIZONA_HiC, are listed below. The full data release can be explored here.
Contig length (bp) | Number of contigs | Contig N50 (bp) | Longest contig (bp) |
|---|---|---|---|
1,072,902,253 | 148,395 | 17,937 | 225,775 |
Scaffold length (bp) | Number of scaffolds | Scaffold N50 (bp) | Longest scaffold (bp) |
|---|---|---|---|

Draft
The chromosome-length genome assembly is based on the draft assembly NIATT_ARIZONA (GCA_002029285.1), credited below.
Murray, Gemma G. R., Andre E. R. Soares, Ben J. Novak, Nathan K. Schaefer, James A. Cahill, Allan J. Baker, John R. Demboski, et al. 2017. "Natural Selection Shaped the Rise and Fall of Passenger Pigeon Genomic Diversity." Science 358 (6365): 951-54. https://doi.org/10.1126/science.aao0960.
Method
3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018). See Methods for more information.
Hi-C sample
The frozen sample for in situ Hi-C preparation was donated by a male individual, and provided to us by Wildlife Conservation Society. We thank WCS for additional samples for this species.
Hi-C Contact maps
Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018).
