Igugu Lesiqhingi

Ukufiphala Okumibalabala kwango-Okthoba
Ingxenye 2: Igugu Lesiqhingi

nguMark J. Spalding

Ngokulandelayo, ngaya eBlock Island, eRhode Island, eqhele ngamakhilomitha angaba ngu-13 (noma ukugibela ihora ngesikebhe) ukusuka ePoint Judith. Ngaba nenhlanhla yokuwina i-raffle ukuze ngizuze i-Rhode Island Natural History Survey—eyanginika isonto lonke eRedgate Farm eBlock Island eduze neNew Harbor. Isonto elingemva koSuku lukaColumbus lisho ukwehla okungazelelwe kwezixuku futhi isiqhingi esihle sinokuthula ngokuzumayo. Ngenxa yemizamo ehlanganyelwe ye-Block Island Conservancy, ezinye izinhlangano, kanye nemindeni ezinikele yaseBlock Island, ingxenye enkulu yesiqhingi ivikelekile futhi ihlinzeka ngohambo oluhle lokuqwala izintaba ezindaweni ezihlukahlukene eziqhingini.  

Siyabonga kubasingathi bethu, uKim Gaffett we-Ocean View Foundation kanye ne-Survey's Kira Stillwell, sibe namathuba engeziwe okuvakashela izindawo ezivikelekile. Ukuhlala esiqhingini kusho ukuthi ujwayelene nomoya—ikakhulukazi ekwindla, futhi, endabeni kaKim noKira, ikakhulukazi ngesikhathi sokufuduka kwezinyoni. Ekwindla, umoya wasenyakatho uwumoya womsila wezinyoni ezifudukayo, futhi lokho kusho amathuba okucwaninga.

Usuku lwethu lokuqala olugcwele, saba nenhlanhla yokuba khona lapho ososayensi abavela e- I-Biodiversity Research Institute babesenza ama-raptors abo okuwa. Lolu hlelo selusonyakeni wesine futhi lubalwa nabalingani bayo i-Ocean View Foundation, i-Bailey Wildlife Foundation, i-Nature Conservancy, kanye neNyuvesi yaseRhode Island. Egqumeni elinomoya obandayo engxenyeni eseningizimu yesiqhingi, iqembu le-BRI lalithwebula ama-raptors amaningi—futhi safika kuyintambama enhle kakhulu. Le phrojekthi igxile emaphethini okufuduka kwama-peregrine falcons kanye nomthwalo onobuthi wama-raptor esifundeni. Izinyoni esasizibuka zazikalwa, zikalwe, zaboshwa, futhi zakhululwa. Ngaba nenhlanhla enkulu yokusiza ekukhululweni kwe-northern harrier yesifazane esencane (eyaziwa nangokuthi i-marsh hawk), ngemva nje kokuba uKim ethathe ithuba lakhe nensizwa encane ye-northern harrier.  

Ososayensi bebelokhu besebenzisa ama-raptor njengama-barometers wezempilo ye-ecosystem amashumi eminyaka. Ukusabalalisa nokuchichima kwazo kuxhumene kakhulu nezingosi zokudla ezizisekelayo. UChris DeSorbo, umqondisi wohlelo, uthi “Isiteshi sokucwaninga iBlock Island raptor sisenyakatho kakhulu futhi sikude kakhulu nogu lolwandle lwe-Atlantic. Lezi zici ezihambisana namaphethini ayingqayizivele okufuduka kwama-raptor lapho zenza lesi siqhingi sibeluleka ocwaningweni nasekuhloleni amandla aso.“ Isiteshi socwaningo saseBlock Island sinikeze imininingwane ebalulekile lapho ama-raptor ethwala umthwalo omkhulu we-mercury, ngokwesibonelo, nokuthi afinyelela kude kangakanani. fuduka.
Izilwane ezifuywayo ezimakiwe ziye zalandelelwa zaze zafinyelela eGreenland naseYurophu—ziwela ulwandlekazi olukhulu ohambweni lwazo. Njengezinhlobo zasolwandle ezifuduka kakhulu njengemikhomo ne-tuna, kubalulekile ukwazi ukuthi abantu bahlukene yini noma inyoni eyodwa ingabalwa ngempela ezindaweni ezimbili ezihlukene. Ukwazi kusiza ukuqinisekisa ukuthi lapho sithola ubuningi bohlobo oluthile, sibala kanye, hhayi kabili—futhi silawula inombolo encane.  

Lesi siteshi esincane se-raptor sesizini sivula iwindi ekuxhumekeni phakathi komoya, ulwandle, umhlaba, nesibhakabhaka-kanye nezilwane ezifudukayo ezincike emisinga ongabikezelwa, ukutholakala kokudla, nezinye izici ukuze zisekele umjikelezo wazo wokuphila. Siyazi ukuthi amanye ama-raptor e-Block Island azobe elapho ebusika, kanti amanye azobe esehambe izinkulungwane zamakhilomitha ukuya eningizimu aphinde abuye, njengoba nje izivakashi ezingabantu zibuya ngenkathi yasehlobo ezayo. Singathemba ukuthi ekwindla elandelayo ithimba le-BRI nabalingani babo bazokwazi ukubuyela ukuze baqhubeke nokuhlola kwabo umthwalo we-mercury, ubuningi, kanye nempilo yezinhlobo eziyisishiyagalombili noma ngaphezulu zama-raptors ezincike kule ndlela.
