　　研究背景和目的理解物種的種間關(guān)系及其影響因子是探究群落集合中非常關(guān)鍵的內(nèi)容,同時(shí)在制定群落保護(hù)計(jì)劃上有重要的實(shí)踐意義。鳥(niǎo)類混合群（Mixedspecies flocks of birds）和鳥(niǎo)類圍攻猛禽時(shí)形成集群是陸地森林中尤為常見(jiàn)鳥(niǎo)類集群。由于許多物種參與混合群和猛禽圍攻,所以這兩種集群是研究鳥(niǎo)類群落中物種相互作用的模式系統(tǒng)。鳥(niǎo)類混合群中一些物種被認(rèn)為是“核心種”（nuclear species）,是社會(huì)信息（social information）的主要提供者,而其他物種（跟隨種,follower species）則利用這些信息來(lái)提高覓食效率和減少捕食風(fēng)險(xiǎn)。目前,這種“核心種-跟隨種”關(guān)系如何響應(yīng)不同捕食風(fēng)險(xiǎn)尚缺乏認(rèn)識(shí);此外,鳥(niǎo)類混合群和圍攻時(shí)形成的集合會(huì)隨著季節(jié)改變,目前尚不清楚這種季節(jié)變化是如何影響信息的產(chǎn)生和物種的角色的;最后,“核心種-跟隨種”關(guān)系研究?jī)?nèi)容主要集中在警戒叫聲和圍攻叫聲,目前還沒(méi)有研究表明跟隨物種是否會(huì)利用核心種的聯(lián)絡(luò)叫聲來(lái)減少捕食風(fēng)險(xiǎn)�；诖�,本研究探索了三個(gè)關(guān)鍵問(wèn)題:1)不同捕食風(fēng)險(xiǎn)的社會(huì)信息是否與混合群中的角色（核心種和跟隨種）相關(guān),以及是否受到季節(jié)的影響...
