Male rhino leg swelling has deteriorated and he is not using it at all now.We have administered antibiotics and more anti-inflammatories using drop out darts this morning. He is not eating or drinking yet. The female was not found this morning after a morning of searching on foot. A helicopter was offered by Warne Rippon to assist with an aerial search but she has still not been seen today. Temperature on the ground is over 35 degrees C so we suspect she is lying up under thicket canopy. Not being able to confirm her status is a concern and the search continues.
