The paper presents the results of the researches performed by the authors between 2000-2019 regarding the biology and the ecology of the species Turdus pilaris L. in the western half of Romania.The extension of the territory, breeding, clutch size, behaviour, number of generations , the phenology and food were studied. The height of nests above the ground varied till to 20 meters in a different trees. The nest is cup – shaped and the material of construction is extremely different : moss, roots, dry twigs, ground mixed with grass, herbs. It presents 2 -3 yearly generations, a complete clutch consists of 5 – 6 eggs. The post – embrionic development lasts 12 – 16 days. The phenology is different : in high hilly and the mountainous areas the species is sedentary, in low hilly and plain areas the species is partial – migratory or passage or in many times winter visitor. The food is extremely different: insects, fruits, worms, spiders, molusca, little mammals.
The paper presents new observations about the phenological anomalies regarding the flowering of spontaneous and cultivated plants from different parts of Romania during the period 2010-2019.The consequences of global warming, these anomalies have become more proeminent particularly in the last eight years (2013-2019) being observed in 36 species of spontaneous and cultivated plants. Flowering extension were observed, sometimes even supplementary flowerings, fecundation and even fructification, in the cold season (November-December) and are due to the positive temperatures from the cold season and the high temperatures from spring. Most phenological anomalies were observed in the following botanical families:
