Effect Of Spring Temperature Change On Migration Time Of Passeriformes In Maoershan,Heilongjiang Province

The process of bird migration is a very complicated physiological process.This behavior is an instinctive response of birds to adapt to nature.Every year,hundreds of millions of birds in the world perform migration behaviors.It can better protect birds,and use migratory bird migration to protect aviation safety,agriculture and forestry protection,and prevent the spread of some epidemics.The migration time of birds is affected by many factors.Some studies have shown that temperature will affect the migration behavior of birds in certain factors.In different temperature seasons,birds will take certain countermeasures in the migration time.In the past,Studies of bird migration time have shown that migration responses to climate change vary widely.In this article,the ring records of 15 species of passerine birds from Ringe Station in Maoershan Forest District,Heilongjiang Province,from 1999 to 2019,and the weather data of the three stations in the vicinity of the Ring Station are used as research data.Make records.Fifteen species of passerine birds from the ring migration during the spring migration of Huanzhi Station were used as the research objects.The first-to-day,peak day,end day and corresponding temperature changes during the migration process Sort out the analysis and try to find out the effect of temperature changes on the migration time of these 15 passerine birds.In general,the migration time of these fifteen species of birds is related to temperature.The first-to-day and daily average temperatures of yellow-throated salamanders,yellow-backed salamanders,gray-backed salamanders,yellow-browed salamanders,and field salamanders(greater than 0?,greater than 5?,greater than 10?)have a positive correlation;the first to the day of the blue-tailed pheasant,passerine,blue songbird,and gray-headed pheasant have a negative correlation with the daily average temperature;The red-throated songbird,giant-billed willow warbler,brown-browed wren,white-browed flycatcher,northern red-tailed wren,and brown willow warbler have no significant first-to-date and daily average temperatures.Sexually related.The peak days of the field salamander,the gray-backed salamander,the yellow-rumped willow warbler,the yellow-throated salamander,the brown-browed salamander,the white-browed salamander,and the daily average temperature are positively correlated.Red-throated songbirds,yellow-browed willow warbler,blue-tailed wagtail warbler,big-billed willow warbler,northern red-tailed wagtail peak day and daily average temperature have a negative correlation;only brown The peak day of Liuying had no significant correlation with the daily average temperature.Tian Yan,Yellow-browed Willow Warbler has a positive correlation with the daily average temperature;yellow-rumped willow warbler,passerine,brown-browed wren,northern red-tailed wren and daily mean temperature negative correlation;red-throated songbird,gray-backed songbird,blue songbird,brown willow warbler,yellow-throated salamander,gray-headed salamander,giant-billed warbler,white-browed flycatcher,There is no significant correlation between the blue-tailed salamander and the daily average temperature.Correlation analysis of the migration dates of fifteen species of passerine birds and the monthly average temperature from February to May shows that the migratory heads of the field salamander,gray-headed salamander,blue-tailed salamander,passerine,brown willow warbler,and blue song salamander There is a positive correlation between the day and the average monthly temperature from February to May;red-throated songbirds,gray-backed salamanders,yellow-rumped willow warbler,yellow-throated salamander,brown-browed rock salamander,giant-billed willow warbler,white-browed flycatcher,northern red tail There was a negative correlation between the first to the day of the migratory migration and the monthly average temperature from February to May;the first to the day of the yellow-browed Liuying had no significant correlation with the monthly average temperature from February to May.Grey-backed owl,gray-headed owl,blue-tailed owl,and brown willow warrior peak migration day have a positive correlation with the average monthly temperature from February to May;Tian ya,yellow-throated salamander,giant-billed warbler,white-browed flycatcher peak day and two The average monthly temperature from month to May showed a negative correlation;the red-throated songbird,the yellow-browed willow warbler,the yellow-rumped willow warbler,the passerine,the brown-browed rock salamander,and the northern red-tailed salamander had no significant correlation with the average monthly temperature from February to May.Red-throated songbird,yellow-rumped willow warbler,northern red-tailed warbler,and brown willow warbler end of migration show a positive correlation with the average monthly temperature from February to May;Tianyu,yellow-throated salamander and monthly average temperature from February to May Negative correlation;Yellow-browed willow warbler,Grey-backed wren,Grey-headed wren,Blue-tailed wren,Finch,Brown-browed wren,Giant-billed willow warbler,White-browed Flycatcher and monthly mean temperature from February to May;no significant correlation The peak and end days of the migration of tadpoles have both positive and negative correlations with the monthly average temperature from February to May.The results showed that the variation coefficient of the first day of migration was the largest,the second was the peak day,and the last day of migration was the smallest,that is,the fluctuation of the first day was the largest.There is a significant correlation between the first arrival day of migration of 15 species of birds and the temperature,and the correlation results are consistent with the variation coefficient results.There is a strong correlation between the peak day of migration and the temperature change,and the correlation between the end day of migration and the temperature is the smallest,and the migration time of the whole birds tends to advance.Therefore,according to the change of temperature,the migration time of migrating birds in spring can be predicted.
