Palestine Sunbird
The Palestine sunbird (Cinnyris osea) is a small, vibrant passerine bird belonging to the Nectariniidae family. Known for its agility and striking appearance, this species is found across parts of the Middle East and sub-Saharan Africa. It is sometimes referred to as the northern orange-tufted sunbird, though this distinguishes it from a separate species of orange-tufted sunbird located further south in Africa.
Beyond its biological significance, the bird holds cultural importance; in 2015, the Palestinian Authority adopted it as the national bird. Its scientific name, osea, is derived from the Ancient Greek word hosia, meaning "holy."
Key Facts
- Scientific Name: Cinnyris osea
- Conservation Status: Least Concern (IUCN 3.1)
- Diet: Primarily nectar and insects
- Size: 8 to 12 cm in length
- National Status: National bird of Palestine
- Distinctive Feature: Males possess glossy plumage and small orange breast tufts
Physical Description and Characteristics
The Palestine sunbird is a compact bird, measuring between 8 and 12 cm in length with a wingspan of 14 to 16 cm. On average, males weigh 7.6 g, while females are slightly lighter at approximately 6.8 g. Both sexes possess a fairly long, black bill that curves downward, an evolutionary adaptation for feeding.
Plumage varies significantly by sex and season. Breeding males exhibit mostly dark feathers that appear glossy blue or green when caught in the light. A defining characteristic of the male is the presence of orange tufts on the sides of the breast, though these are typically only visible at close range. Females and juveniles are more understated, featuring grey-brown upperparts and pale underparts. Non-breeding males resemble the females but may retain some of their dark plumage.
In terms of vocalization, the species is known for a high, fast, jingling song, as well as a harsh alarm call used to warn others of danger.

Habitat and Distribution
These birds thrive in dry climates with high temperatures, ranging from sea level up to altitudes of 3,200 meters. Their preferred habitats include dry woodlands, scrublands, wadis (dry riverbeds), savannas, orchards, and gardens. Due to their adaptability, they are common sights in urban areas.
Regional Subspecies
- C. o. osea: This Middle Eastern subspecies breeds in Israel, Palestine, and Jordan, extending south through western Saudi Arabia to Yemen and Oman. In recent decades, it has expanded into Egypt's Sinai Peninsula and is observed breeding in Lebanon, where it also winters along with populations in Syria. The spread of this subspecies has been aided by urban expansion and the increased planting of tropical garden plants.
- C. o. decorsei: This African subspecies is found in more localized areas, including parts of Sudan, north-west Uganda, the Central African Republic, north-east Democratic Republic of Congo, and northern Cameroon.
Diet and Feeding Habits
The Palestine sunbird is primarily a nectarivore, though it also consumes insects. To facilitate the extraction of nectar from flowers, the bird possesses a specialized long, brush-tipped tongue.
Reproduction and Nesting
The nesting process of the Palestine sunbird is a feat of natural engineering. They build purse-like nests that hang from the branches of trees or bushes. These nests measure approximately 18 cm in length and 8 cm in width at the base.
Construction materials include leaves, grass, and other plant matter, which are bound together using spider webs and hair. The interior is lined with soft wool and feathers for insulation. A clutch typically consists of one to three smooth, glossy eggs, which are white or grey with faint markings. After an incubation period of 13 to 14 days, the young hatch. These downy chicks, characterized by their orange-red mouths, fledge after 14 to 21 days.

Frequently Asked Questions
What is the difference between the Palestine sunbird and the orange-tufted sunbird?
While the Palestine sunbird is sometimes called the northern orange-tufted sunbird, the name "orange-tufted sunbird" specifically refers to a different species found further south in Africa.
Why has the Palestine sunbird spread in urban areas?
The expansion of cities and villages, particularly in Israel, has led to an increase in cultivated tropical plants in urban gardens, providing more food sources and habitats for the birds.
What do Palestine sunbirds eat?
Their diet consists mainly of nectar, which they extract using a specialized brush-tipped tongue, supplemented by insects.
How do Palestine sunbirds build their nests?
They create hanging, purse-like nests using leaves and grass, bound together with spider webs and hair, and lined with feathers and wool.
What is the conservation status of the Palestine sunbird?
The species is currently classified as Least Concern by the IUCN (version 3.1).
