Feb (wild female orangutan) is Pregnant!

Written by Azis (Orangutan Project Coordinator)

When I followed Feb, a wild adult female orangutan in the Sabangau Forest, I saw very different behaviour than normal.  I could also see that her belly was very big! Normally Feb is more active, whereas this time she was slow and resting a lot. So I had the thought that maybe she is pregnant. The day after that I tried to collect her urine for a pregnancy test to see if she was pregnant or not. When I took a test in the forest it was negative.

The positive pregnancy test! The same pregnancy test kits that humans use are effective in detecting orangutan pregnancy too

When I saw the results I was disappointed, but I felt sure that Feb was pregnant. She was very large in her stomach and she had swollen genitals, which can indicate pregnancy, and a few months ago we saw her mating with a male. So I tried another test in camp, just in case the test was wrong. Good news!! Feb is pregnant!

All the team are very excited and can’t wait to see Feb’s new baby. We are already starting to think about names for the baby. We need to think long and hard because we need to get a name which is awesome for Feb’s new bundle of joy!


Feb and her offspring, Fio. He is breastfeeding, but he will need to stop by the time the baby comes. He is about 7 years old so he should be ready to become more independent from Feb in time for the arrival of his younger sibling.

Ketika saya mengikuti Feb, orangutan betina dewasa yang hidup liar di Hutan Sabangau, saya melihat perilaku yang sangat berbeda dari biasanya. Saya bisa melihat kalau perutnya sudah membesar. Feb biasanya lebih aktif beraktivitas, sedangkan sekarang dia terlihat lebih santai dan lebih banyak beristirahat. Jadi saya berpikir, mungkin dia sedang hamil, tetapi saya masih belum yakin dengan perkiraan ini. Keesokan harinya saya mencoba mengambil urin Feb untuk melakukan tes kehamilan apakah dia hami atau tidak. Ketika saya mencoba melakukan tes di dalam hutan, hasilnya menunjukkan negatif.

Saya merasa kecewa sekali ketika melihat hasil negatif ini, tetapi saya yakin kalau Feb sedang hamil. Perutnya terlihat sangat besar dan kemaluannya bengkak, yang menjadi tanda kehamilan, dan kami juga melihat dia kawin bersama jantan besar beberapa bulan lalu. Jadi, saya coba lakukan tes lagi di kamp dengan testpack  yang berbeda, mungkin yang sebelumnya salah. Kabar gembira! Feb hamil!

Semua tim sangat senang dan tidak sabar untuk melihat bayi baru Feb. Kami sudah mulai memikirkan nama untuk si bayi. Kami perlu berpikir keras dan cukup lama karena kami mau menadapatkan nama yang bagus untuk bayi Feb.

 

Exciting news! Our Orangutan Project Coordinator, Azis, and the Orangutan Scientist, Sophie, are very excited by this positive pregnancy test.
