The Turtle Dove (Streptopelia turtur) is a small, migratory species of dove known for its delicate appearance and distinctive vocalization. It is smaller and darker than the common Collared Dove, featuring a pale gray-lilac head, a pinkish chest, and a tail with a thin white edge. Its most identifying feature is the patch of black and white stripes on the side of its neck and the intricate, tortoiseshell-like pattern of chestnut and black on its wings. The species gets its name from its characteristic, low, gentle purring sound, often transcribed as a vibrating “turrr, turrr,” which signals its arrival in the spring.
Defining the Geographic Range
The Turtle Dove is a long-distance migrant whose annual cycle spans separate breeding and wintering ranges. During the summer breeding season, the dove covers the southwestern Palearctic, stretching across most of Europe and Western Asia. This northern range extends from Spain and France eastward into parts of China and Central Asia, also including North Africa.
The entire population migrates southward to spend the winter months in sub-Saharan Africa, just north of the equator. These wintering grounds form a band across the continent, primarily encompassing the Sahel region of West Africa. Doves are found in countries like Senegal, The Gambia, Mali, and Mauritania, extending eastward into Sudan and Ethiopia. This pattern classifies the Turtle Dove as a trans-Saharan migrant, relying on suitable conditions across two continents.
Specific Habitat Selection
The Turtle Dove seeks specific micro-environments within its ranges for nesting, foraging, and roosting. In European breeding grounds, the species prefers a mosaic of open woodland edges, dense scrub, and agricultural landscapes. Optimal breeding habitat includes mature, thorny scrub or tall, thick hedgerows, which provide the dense cover necessary for building nests. They generally avoid large forests and overly urbanized areas, favoring habitats where woodland and farmland meet.
Foraging areas must contain an abundance of small, accessible seeds, primarily from weeds like fumitory and chickweed, which they pick from bare ground. Access to shallow, clean water sources for drinking and bathing is also necessary during the breeding season. Conversely, in the West African wintering grounds, the doves concentrate in dry savannah and acacia woodlands. They establish a home range centered around a roost site, often a clump of thorny Acacia trees that offers protection from predators.
The Annual Migration Cycle
The Turtle Dove is one of the last summer migrants to arrive in Europe, typically appearing in northern regions from mid-April to early May, and departing in autumn between July and September. The birds follow what is often termed the “Western Flyway,” a major corridor that funnels the Western European breeding population south through France, across the Pyrenees, and into Spain and Morocco.
The migration is characterized by nocturnal flights, with birds traveling up to 700 kilometers without stopping, and daytime rest periods at stopover sites. A major ecological barrier is crossing the Mediterranean Sea, followed by the Sahara Desert, which presents a significant energetic challenge. Birds must stop over to refuel, often for one to two weeks in areas like northern Algeria and Morocco, before or after crossing the desert. These stopover sites are necessary for accumulating the fat reserves needed to survive the journey and are used during both the southward and northward movements.
Conservation Status and Population Decline
The European Turtle Dove population has undergone a severe decline across its range, leading to its classification as Vulnerable on the IUCN Red List. The primary driver of this decline is a lack of sufficient food resources in the European breeding grounds, leading to significantly reduced breeding success. Changes in modern agricultural practices, such as the increased use of herbicides and the removal of weedy field margins, have decimated the supply of small seeds the doves rely on to feed their young. This scarcity means breeding pairs often rear only a single clutch of chicks, rather than the multiple clutches necessary to sustain the population.
A second major factor is unsustainable hunting pressure along the migratory flyway, particularly in passage countries in Southwestern Europe. Historically, high numbers of doves were legally shot each autumn in countries like France, Spain, and Portugal, which prevented the recovery of the Western European population. While a moratorium on hunting in the Western Flyway has since been implemented, illegal hunting remains a concern in parts of the Mediterranean, where birds stop to rest after crossing the Sahara. The combination of low productivity in Europe and high mortality during migration requires focused international efforts to protect the species across its entire annual range.
