No. Northern cardinals are classified as Least Concern by the IUCN. Their population is stable, estimated at over 120 million breeding individuals, and has actually been expanding northward for decades.
Quick Facts
| IUCN status | Least Concern |
| Population trend | Stable to increasing |
| Estimated population | 120 million+ |
| Range | Eastern US, Mexico, Central America - expanding north |
| Legal protection | Migratory Bird Treaty Act (1918) |
Why They Are Doing Well
Cardinals are generalists. They eat seeds, fruit, and insects. They nest in gardens, parks, forests, and suburbs. They visit feeders readily and have benefited enormously from the popularity of backyard birdwatching.
Their range has pushed steadily north over the past century. Cardinals were once rare in New England and southern Canada. Now they are year-round residents in both, largely because winter bird feeders give them a reliable food source through the coldest months.
What Does Threaten Them
Cardinals are not endangered, but they are not immune to danger.
- Cats - Domestic and feral cats are the single biggest killer of songbirds in North America. Cardinals, as ground foragers, are especially vulnerable.
- Window strikes - Males attacking their own reflections can injure or kill themselves. This peaks during breeding season when territorial aggression is highest.
- Pesticides - Insecticides reduce the insect prey that cardinals need, particularly when feeding chicks.
- Habitat loss - Urban sprawl removes nesting cover, though cardinals adapt to gardens better than most species.
The Yellow Cardinal (Gubernatrix cristata) of South America is a different story entirely - it is genuinely endangered due to illegal trapping for the pet trade. Do not confuse it with the northern cardinal’s rare yellow colour morph.
Legal Protection
In the United States, it is illegal to capture, keep, sell, or kill a cardinal under the Migratory Bird Treaty Act. Penalties include fines up to $15,000 and up to six months in prison. Canada provides similar protection under the Convention for the Protection of Migratory Birds.
In parts of Europe, cardinals are kept as aviary birds under special licensing. This requires permits from wildlife authorities and does not apply to wild-caught birds.
How You Can Help
- Keep cats indoors - The single most effective thing any homeowner can do for songbirds
- Break up window reflections - External decals, soap, or tape stop territorial males from injuring themselves
- Feed consistently - Black oil sunflower seeds in a platform feeder, especially through winter
- Plant native shrubs - Holly, dogwood, and juniper provide nesting cover and natural food
