Justification: This species has declined over the long term and apparently continues to do so at a moderately rapid rate. It is therefore considered to be Near Threatened. |

| History: |
|
|||
| Range Description: | Passerina ciris occurs in two geographically disjunct populations: a western population breeding from northern Mexico to northern Texas, USA, and wintering in south-west Mexico; and an eastern population breeding along the Atlantic coast from North Carolina to Florida (USA) and wintering in southern Florida and the Caribbean3. The global population is estimated to be 3.6 million birds7. Populations have declined since the mid-1960s and the species has been extirpated from parts of its range in south-west and east USA and north-east Mexico3,4,8,9. Breeding Bird Survey data from the continental USA (and for five years from north-east Mexico) indicates that the population has declined by 55% over the last 30 years2,7, with the steepest declines in the eastern population. |

| Population Trend: |
Decreasing
|
| Habitat and Ecology: | The western population breeds in scrub-brush habitat that remains largely intact, and the eastern population inhabits coastal plain agricultural land3. |
| Systems: | Terrestrial |
| Major Threat(s): | Loss and intensification of habitat through urban development, road building and agricultural intensification, and capture for the cagebird trade are the primary threats2,3,5, with part of the declines also being attributed to brood-parasitism by Brown-headed Cowbird. Trapping and sale in local markets occurs in Mexico, Central America and the Caribbean, and overseas to international markets in Europe, South America and Asia1,2,6. |
| Conservation Actions: |
Conservation Actions Underway The species is monitored, but no other specific actions are known. Conservation Actions Proposed Tightly control any ongoing trade in the species. Develop an appropriate management strategy to reverse population declines. Develop a comprehensive conservation strategy including adaptive harvesting for populations in the Caribbean and Latin America10. |
