Purple Grenadier
Granatina ianthinogaster
Visual Identification
Appearance
The Purple Grenadier is a striking small finch. Males showcase vibrant blue and purple plumage. Their bodies are predominantly violet-blue, contrasting with a chestnut-brown belly and flanks. The face features a distinctive red mask around the eyes.
Females are less colorful, with mostly brown plumage, but still display a blue tail and rump. Both sexes have red beaks and pink legs, contributing to their eye-catching appearance.
Juveniles are quite similar to females, but they lack patches on the face and the spots and barring on the chest.

Distribution
Purple Grenadiers inhabit savanna and grassland regions across eastern Africa, from Ethiopia and Somalia south to Tanzania and east to Kenya. They prefer areas with scattered trees and shrubs, often near water sources.
These birds are non-migratory, maintaining their presence in suitable habitats year-round. They may make local movements in response to seasonal changes in food availability or rainfall patterns.

Distribution Map
This map gives you a rough idea of where you might spot a Purple Grenadier. 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

Share your thoughtsBird 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

Agility
Reflects the bird's manoeuvrability, speed, and grace in flight or movement.
The Purple Grenadier displays considerable agility with its bouncy flight pattern and energetic hopping between branches. Their ability to cling to grass stems whilst foraging also indicates good manoeuvrability.
Strength
Indicates the bird's physical power, often correlating with size and hunting abilities.
As a small finch weighing only 10-14 grams, the Purple Grenadier has limited strength. However, they possess enough power to construct nests and forage effectively.
Adaptability
Represents the bird's ability to thrive in various environments or changing conditions.
Purple Grenadiers show adaptability by inhabiting areas up to 2,000 metres in elevation and making local movements in response to food availability and rainfall patterns. Their varied diet of seeds and insects also demonstrates flexibility.
Aggressiveness
Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.
Whilst not particularly aggressive, male Purple Grenadiers engage in elaborate courtship displays and defend their territories during breeding season. They are generally social birds, often seen in flocks.
Endurance
Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.
These small birds demonstrate moderate endurance through their non-migratory lifestyle and ability to survive in varied savanna and grassland habitats. Their capacity to forage actively and care for young also suggests reasonable stamina.
Diet
Purple Grenadiers primarily feed on small seeds from grasses and other plants. They supplement their diet with insects, especially during the breeding season, particularly termites and small spiders.
These birds are often seen foraging on the ground or clinging to grass stems to reach seed heads.
Behaviour
Purple Grenadiers are social birds, often seen in small flocks or pairs. They exhibit a bouncy flight pattern and are known for their energetic hopping and flitting between branches while foraging.
During courtship, males perform elaborate displays, puffing out their feathers and singing to attract females.
Vocalisation
Purple Grenadiers are fairly vocal birds, and have a pleasant, melodious song consisting of soft warbles and trills. Their calls include a variety of gentle chirps and tweets, often described as 'tseee-tseee' or 'zwee-zwee'.
During courtship, males produce more elaborate and prolonged singing performances.
Nesting & Breeding
Breeding occurs during the rainy season, typically between March and May. Males court females with elaborate displays and soft songs. Pairs form monogamous bonds for the breeding season.
For the courtship display, males will either hold a grass stem or feather in their beaks and bob up and down near a female. They will then stretch the neck will the bill facing up before bowing the head side to side. Interesting females will fly over to the male and sometimes join in with the bobbing up and down.
Nests are spherical structures made of grass, lined with soft materials, and often hidden in dense vegetation or low bushes. Females lay 3-5 small white eggs per clutch.
Both parents share incubation duties, which last about 12-14 days. Chicks fledge after approximately 3 weeks but may remain with their parents for several more weeks before becoming fully independent.
Conservation and Status
Global Conservation Status
Currently listed as Least Concern by the IUCN, Purple Grenadiers have a stable population across their range. However, they face localized threats from habitat loss due to agricultural expansion and overgrazing.
Conservation efforts focus on maintaining suitable savanna and grassland habitats.
Birdwatching Tips
- Look for Purple Grenadiers in open savanna and grassland areas with scattered trees and shrubs.
- Listen for their soft, melodious warbling calls to locate them.
- Observe them near water sources, especially during dry seasons.
- Use binoculars to spot their distinctive red eye masks and vibrant plumage.
- Although fairly common throughout their range, they are quite secretive birds and are often found foraging in a pair, small group or on their own
Additional Information
Quick Facts
Predators
Main predators include small raptors such as sparrowhawks, shrikes, and occasionally snakes that raid nests for eggs and chicks.
Did You Know?
- Male Purple Grenadiers can change the intensity of their blue plumage to appear more attractive during courtship.
- These birds are sometimes kept as pets due to their vibrant colors and pleasant songs.
- Purple Grenadiers often associate with other finch species in mixed feeding flocks.
