| Feature | Northern Cardinal | Scarlet Tanager |
|---|---|---|
| Scientific Name | Cardinalis cardinalis | Piranga olivacea |
| Length | 8.3–9.1 in (21–23 cm) | 6.3–7.5 in (16–19 cm) |
| Wingspan | 9.8–12.2 in (25–31 cm) | 9.8–11.4 in (25–29 cm) |
| Weight | 1.2–1.7 oz (34–45 g) | 0.8–1.4 oz (23–38 g) |
| Overall Shape | A plump, long-tailed songbird with a tall crest and a thick, seed-cracking bill | A stocky, thick-billed forest songbird that keeps to the leafy canopy |
| Male Plumage KEY | Brilliant all-over red with a black mask around the bill, tall crest, orange-red bill | Breeding male blood-red with jet-black wings and tail; in winter, yellowish-green like the female but with black wings |
| Female Plumage | Warm buff-brown with red tinges on the wings, tail and crest; same black mask and orange bill | Yellowish-olive below, darker olive above, gray-brown wings — no black anywhere |
| Bill Shape | Very thick, conical, orange-red — built for crushing large seeds | Thick, pale gray-horn colored — thinner than a cardinal’s, thicker than a warbler’s |
| Tail | Long and rounded, often flicked sideways as it feeds low | Medium, dark in the male, olive in the female |
| Core Range | Eastern and central US, the Southwest and southern edges of Canada; expanding northward | Breeds in mature eastern deciduous forest; winters in northern South America |
| Migration KEY | Non-migratory — a mated pair may hold the same yard all year | Long-distance migrant — arrives in May, gone by early fall |
| Feeder Presence KEY | Sunflower and safflower on platform feeders or the ground beneath; prefers nearby cover | Rare at feeders; may come for orange halves, jelly or mealworms during migration |
| Favorite Foods | Seeds, sunflower, safflower, cracked corn, fruit; insects in summer | Insects gleaned high in oaks; fruit during migration and on the wintering grounds |
| Song | Clear, loud whistles — “cheer-cheer-cheer” or “birdie-birdie-birdie”; females also sing | Burry, robin-like phrases — a robin with a sore throat |
| Flight Call | A sharp, metallic “chip” | A distinctive “chip-burr” — short note plus a buzz |
| Population Trend | Stable and expanding; one of the most familiar backyard birds in the East | Stable overall but sensitive to forest fragmentation |

- Thick orange bill and a long, rounded tail.
- Sings clear whistles from an exposed perch even in winter.
Scarlet Tanager — Male

Female & Juvenile Marks, Side by Side

Song & Call Comparison
Northern Cardinal
Song: clear, repeated whistles — cheer-cheer-cheer, birdie-birdie-birdie.
Calls: a sharp metallic chip; pairs call back and forth in cover.
Scarlet Tanager
Song: burry, robin-like phrases with a rough edge.
Calls: the diagnostic chip-burr — learn it and find more tanagers.
Range & Seasonal Presence
The Northern Cardinal is a non-migratory resident of the East, Midwest and Southwest, expanding steadily north into Canada.
The Scarlet Tanager breeds in mature deciduous forest of the East and winters in South America — present only May through September, and mostly in the canopy.
Feeder Behavior & Favorite Foods
- Northern Cardinal: a devoted feeder bird — sunflower and safflower on platforms or the ground, at dawn and dusk especially.
- Scarlet Tanager: rarely visits feeders; orange halves, jelly or mealworms may tempt one during migration.
- Winter rule: any red bird at a snowy feeder is a cardinal.
- Summer rule: a red-and-black bird singing high in the oaks is the tanager.
Temperament & Flock Behavior
Northern Cardinals are bold, territorial yard birds; pairs stay together and males attack their own reflections.
Scarlet Tanagers are deliberate forest birds — sluggish for their brilliance, singing hidden in leafy crowns.
