Приметы весны: поёт большая синица
Tits in Moscow continue to sing at all!
The protocol of our study suggests that, after the three days of singing tits, we believe that the beginning of spring singing recorded. And so, after the first timid songs 6, 7 and 8 February, tits and began to sing confidently throughout the area of observation. Moreover, when we observe the seasonal changes in plant life, then within the metropolis we usually see very significant difference in the timing of the events up to plus or minus two weeks. Birds sang the same time all over Moscow! That is, at least, for Moscow, we see that the seasonal effects are more stable for animals may be less dependent on the particular microclimate areas. Let's check this assumption with data from other participants from other localities.
