Laughing Dove (Spilopelia senegalensis) Science Article 2 abstract Phenotypic flexibility in basal metabolic rate (BMR) in response to short-term thermalacclimation was assessed in the Laughing Dove (Streptopelia senegalensis), a commonresident bird species distributed throughout most of southern Africa.

Do sympatric doves Streptopelia spp. overlap their vocal activities?
Laughing Dove (Spilopelia senegalensis) Science Article 4 abstract Diurnal vocal activity of three Streptopelia species living sympatrically was analysed. Thedoves showed similar patterns of vocal activity during the day. This suggests that the three species donot avoid acoustic interference by differentiating their vocal activity patterns.

To trill or not to trill? Territorial response to a heterospecific vocal trait in male collared doves, Streptopelia decaocto
Collared-Dove (Streptopelia decaocto) Science Article 3 abstract Responding of individuals outside the conspecific range has been largely explained by biases in sensory or cognitive systemstoward particular traits or trait values. More recently, it has been shown that such responses might occur if individuals stillrespond to signal traits that have been lost over time. Jean Secondi […]
Nonlinear phenomena and song evolution in Streptopelia doves
Collared-Dove (Streptopelia decaocto) Science Article 1 abstract The production of complex bird song is commonly achieved through neuromuscular activity of respiratory,syringeal and craniomandibular systems. According to nonlinear dynamics theory, however, complexity can also emergespontaneously from very simple and deterministic systems, without any external control. Thus far, studies linking bird songcomplexity with nonlinear dynamics are very […]
The expansion velocity of the Collared Dove Streptopelia decaocto population in europe.
Collared-Dove (Streptopelia decaocto) Science Article 2 abstract Invasion models have been developed and applied for a long time. As presently existing models have serious drawbacks, another, more general mathematical model of range expansion has been developed. Using information on reproduction, survival, and dispersal at the level of the individual, this model allows the calculation of […]

Mauritius Blue-pigeon (Alectroenas nitidissima)
The story When the first Dutch mariners landed on Mauritius, they were hungry after weeks at sea on meager rations. Naturally, they caught Dodos and ate them. Soon, however, they tired of the rather tough meat on these easily caught creatures and turned their attentions to smaller, tastier birds. Among those that they mentioned particularly […]
Passenger Pigeon (Ectopistes migratorius)
The story The celebrated Passenger Pigeon has, perhaps, the most extraordinary story of any extinct bird. It may once have been the most numerous bird on Earth, and at the start of the nineteenth century vast flocks of this species blackened American skies. Yet during the course of 100 years the tremendous numbers dwindled until […]
Rodrigues Pigeon (Alectroenas rodericana)
The story This species is known from bones discovered on Rodrigues during the 1870’s and described by Alphonse Milne-Edwards, the celebrated expert on fossil birds at the Paris museum. Milne-Edwards described the species primarily on the evidence of a sternum, and chose to assign it to the genus Columba, whereas later researchers have shown an […]
Ryukyu Woodpigeon (Columba jouyi)
The story This species, closely related to the last, occurred on the Ryukyu and Daito Islands, another of the island groups to the south of Japan. It was last recorded on the Daito Islands during 1936. Although certainly extinct on Okinawa where it was last seen in 1904, the species may possibly cling to existence […]
