Portada de احمد حماد الحسيني: هجرة الحيوان (ePUB)

تَعكسُ الطيورُ والأسماكُ والثديياتُ وغيرُها من الكائناتِ تعقُّدَ نظامِ الحياةِ وديناميَّتَه. وهذا الكتابُ يَكشفُ عن أحدِ مَظاهرِ هذا النظامِ حين يَتناولُ ظاهرةَ الهجرةِ في مَملكةِ الحيوان، فيَكشفُ عن التكيُّفِ الفِطريِّ والتلقائيِّ للكائناتِ على مُختلِفِ درجاتِها وفئاتِها، وما يُعانِيه بعضُ هذه الكائنات، حتى إنَّها أحيانًا تَفقدُ حياتَها في سبيلِ هِجرتِها بحثًا عن القُوتِ والمُناخِ المُلائِم، كما تتبايَنُ المسافاتُ التي تقطعُها مُهاجِرةً؛ بين المسافاتِ القصيرةِ التي تَستغرِقُ بضعَ ساعات، والمسافاتِ الطويلةِ التي تَستغرِقُ بضعةَ أشهُر
