Visual Identification

Appearance

The Red-winged Blackbird is a striking bird with a compact body and rounded wings. Males are glossy black with bright red shoulder patches bordered by yellow, often visible during flight and displays.

Females are dramatically different, with brown-streaked plumage and a pale eyebrow. Juveniles resemble females but have more reddish-brown tones and less defined streaking.

Distribution Map

This map gives you a rough idea of where you might spot a Red-winged Blackbird. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

  • Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
  • Where birds live can change with seasons and available food
  • This map is quite simple - it doesn't show exact locations

We're working on making our maps even better! Soon, we hope to show you:

  • More detailed maps for bigger countries, including state and region
  • How birds move around during different seasons

Bird Attributes Explained

Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.

Attribute Categories:
  • Agility: Manoeuvrability, speed, and grace in flight or movement.
  • Strength: Physical power, often correlating with size and hunting abilities.
  • Adaptability: Ability to thrive in various environments or changing conditions.
  • Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
  • Endurance: Stamina, often seen in migration patterns or foraging behaviours.

Understanding the Ratings:

  • 0-20: Very Low
  • 21-40: Low
  • 41-60: Average
  • 61-80: High
  • 81-100: Very High

Remember, these attributes are relative to other bird species and don't necessarily indicate superiority.

Tap the icon next to each attribute for more information.

Agility 75

Agility

Reflects the bird's manoeuvrability, speed, and grace in flight or movement.

The Red-winged Blackbird demonstrates considerable agility in flight and whilst foraging. Their ability to navigate through dense marsh vegetation and perform aerial displays suggests above-average manoeuvrability.

Strength 40

Strength

Indicates the bird's physical power, often correlating with size and hunting abilities.

Whilst not particularly strong for their size, Red-winged Blackbirds possess adequate strength for their lifestyle. They can defend territories and carry nesting materials, but are not known for exceptional feats of strength.

Adaptability 85

Adaptability

Represents the bird's ability to thrive in various environments or changing conditions.

These birds show remarkable adaptability, thriving in various habitats from wetlands to agricultural fields. Their ability to adjust their diet seasonally and form large flocks outside breeding season further demonstrates their adaptiveness.

Aggressiveness 70

Aggressiveness

Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.

Male Red-winged Blackbirds are notably aggressive during breeding season, vigorously defending territories and displaying confrontational behaviour. This aggression, however, is largely seasonal and context-specific.

Endurance 65

Endurance

Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.

Their ability to form massive winter roosts and undertake partial migrations suggests good endurance. However, as small birds, they likely have limitations compared to larger, long-distance migrants. Their wide distribution across elevation ranges also indicates decent stamina.

Diet

Red-winged Blackbirds are omnivorous, with a diet that varies seasonally. During the breeding season, they consume insects, spiders, and other small invertebrates.

In fall and winter, they switch primarily to seeds, including those from grasses, weeds, and waste grain in agricultural fields.

Behaviour

Red-winged Blackbirds are highly social, often forming large flocks outside the breeding season. Males are territorial during breeding, perching prominently and displaying their red epaulets while giving their distinctive 'conk-la-ree' call.

They forage on the ground or in low vegetation, probing for insects and seeds.

Vocalisation

The male's song is a distinctive 'conk-la-ree' or 'o-ka-lee', often accompanied by a display of his red shoulder patches. Females produce a series of chit or check calls.

Both sexes use various chips and chatters for communication within flocks and during territorial disputes.

Nesting & Breeding

Breeding season for Red-winged Blackbirds typically begins in late spring. Males establish territories and attract females with conspicuous displays and vocalizations.

Females construct cup-shaped nests using grasses and sedges, often woven around several upright stems in marshy vegetation. They lay 3-4 pale blue-green eggs with dark markings.

Incubation lasts about 11-13 days, performed solely by the female. Nestlings fledge after 11-14 days, with both parents contributing to feeding the young.

Conservation and Status

Global Conservation Status

Least Concern [1]

While Red-winged Blackbirds are currently listed as Least Concern, they face threats from habitat loss and agricultural practices.

Conservation efforts focus on preserving wetlands and promoting bird-friendly farming methods to maintain their widespread distribution.

Population Data

Global Population Estimate

180,000,000 mature individuals [2]

Global Population Trend

Trend data may be uncertain or fluctuating

Birdwatching Tips

  • Look for males perched on cattails or reeds in wetlands
  • Listen for the distinctive 'conk-la-ree' call of males
  • Observe large flocks in agricultural fields during winter
  • Watch for the flash of red when males take flight
