Conversely, warmer springtime temperatures can disrupt the synchrony between the two species' nesting periods, potentially mitigating deadly conflicts. The research indicates that male flycatchers have been arriving earlier over the past 30 years, irrespective of springtime temperature trends, highlighting the complex interplay of environmental factors. The study, published in the journal Current Biology, found that conflicts between these bird species are intensifying when certain shifting factors align, leading to the deaths of up to one in ten male flycatchers. While the current death toll does not appear to significantly impact the overall flycatcher population, potentially because the majority of victims are late-arriving males with lower mating success, there is a concern that increasing numbers of resident birds due to climate change could lead to more severe consequences for migrants upon their arrival at breeding grounds, including potential eviction or fatal confrontations.",{"@graph":14,"@context":49},[15,34],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/mistimed-migration-means-bird-death-battles/24357",4,{"url":32,"name":10,"@type":35,"author":36,"headline":10,"publisher":39,"fileFormat":42,"description":12,"dateModified":43,"datePublished":43,"encodingFormat":42,"isAccessibleForFree":44,"interactionStatistic":45},"DigitalDocument",{"name":37,"@type":38},"Logic","Person",{"url":19,"name":40,"@type":41},"DocShare","Organization","application/pdf","2026-05-07",true,{"@type":46,"interactionType":47,"userInteractionCount":4},"InteractionCounter",{"@type":48},"ViewAction","https://schema.org",{"og:url":32,"og:type":51,"og:title":10,"og:site_name":40,"og:description":12},"article",{"robots":53,"canonical":32},"index,follow",{"doc_id":55,"site_id":7},24357,1778188644,{"code":4,"msg":58,"data":59},"success",{"doc_id":55,"user_id":60,"nickname":37,"user_avatar":61,"doc_module":4,"category_id":62,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":11,"file_id":63,"file_url":64,"file_type":65,"file_size":66,"view_count":4,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":67,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":11,"faqs":11,"seo_title":68,"seo_description":12,"update_tm":56,"read_time":30},1099513958762,"https://ap-avatar.wpscdn.com/avatar/1000023916a998db790?x-image-process=image/resize,m_fixed,w_180,h_180&k=1784791008015729253",8,"cbCaicRjDNZC7iuE","https://ap.wps.com/l/cbCaicRjDNZC7iuE","pdf",185277,"English","Mistimed Migration Means Bird Death Battles | PDF",{"code":4,"msg":58,"data":70},[71,75,79,83,88,93,98,101,106,109,113],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":72,"show_sort_weight":73,"slug":74},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":76,"show_sort_weight":77,"slug":78},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":80,"show_sort_weight":81,"slug":82},"Exam",70,"exam",{"id":84,"doc_module":4,"doc_module_name":25,"category_name":85,"show_sort_weight":86,"slug":87},5,"Comic",60,"comic",{"id":89,"doc_module":4,"doc_module_name":25,"category_name":90,"show_sort_weight":91,"slug":92},6,"Technology",50,"technology",{"id":94,"doc_module":4,"doc_module_name":25,"category_name":95,"show_sort_weight":96,"slug":97},7,"Healthcare",40,"healthcare",{"id":62,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":99,"slug":100},30,"research-report",{"id":102,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},9,"Religion & Spirituality",20,"religion-spirituality",{"id":104,"doc_module":4,"doc_module_name":25,"category_name":107,"show_sort_weight":104,"slug":108},"World Cup","world-cup",{"id":110,"doc_module":4,"doc_module_name":25,"category_name":111,"show_sort_weight":110,"slug":112},10,"Lifestyle","lifestyle",{"id":114,"doc_module":4,"doc_module_name":25,"category_name":115,"show_sort_weight":84,"slug":116},19,"General","general"]
