This is our last observation scheduled on the protocol for Renee’s graduate research!  My highlight was watching the courtship interactions between Lucifer (M530B) and F63Y.  When he stopped mounting her, she mounted him!

When I first located Lucifer, he was off the road between the Addax shed and Turtle Pond.  He was grazing on a patch of green grass across from where the juniper has been cleared.  He then walked toward the Safari Camp and I picked him up again on the Juniper Loop.

F63Y found Lucifer and approached him.  He courted her intensively, including foreleg lift, horn taps, following and mounting.  When his interest waned, she reciprocated with foreleg lift, horn(less) taps, following and mounting.  The video is in sequential 6-min focals, about 24-30 minutes total.

The pair moved toward a group of 10 female waterbuck on the main meadow near the clinic.  Although the other females moved on, Lucifer and F63Y remained grazing.

The next morning, I found the females and Lucifer in the same location before daylight.  The other females moved to the Juniper Loop at daybreak.  Lucifer followed them, as they entered the woods south of Safari Camp.  I did not locate him for the rest of the day.

Renee will fill in more details about what was observed….

These are the highlighted behaviors and events of M530B in the main pasture

8-4-09

7pm to sunset- M530B grazed with 5 females about 35 yards away in the opening before crossing the creek towards the Lodge. They moved slowly and eventually crossed the road near the addax and white-tailed deer. Five male white-tailed came running from the southeast which spooked all the females and the addax. M530B just watched as they went by.

8-5-09

7am- M530B was courting an untagged female as two other females darted and ran away them. He went out of view at 740am. They were in the same spot from previous night.

8am- M530B was in juniper loop standing over a female with an erection.

9am- He was grazing near 4 females in juniper loop.

925am- He was courting an untagged female. They stood next to each other and then he moved to lay down near the other females.

After 11am I could not find him all day.

6pm-he was spotted in juniper loop courting a female. She was untagged and she did a chin rub on his rear. She continued to court him while he grazed or just stood there. She would walk away and he followed. They both grazed and then either her or him would approach another to begin courtship. This seemed like a process that kept repeating itself until sunset. As a side note, she approach my car while she was grazing. I have not experienced a waterbuck walking up to the vehicle like the addax until now.

8-6-09

730am- M530B was at the west end of juniper loop with the same female. He mounted her and was successful. This was the first time seeing him complete a courtship with a successful mount.  Afterwards, she mounted him and she did a chin rub on his rump. He was grazing and then they stood next to each other for a while. They grazed and went out of view towards the waterbuck shelter.

Lets dialogue about birthing behavior here…

The highlight was a tremendous thunderstorm Saturday afternoon with rainbows in the evening!  During the storm, the waterbuck huddled under trees. When the rain slowed down, they grazed, occasionally shaking water droplets off their heads.

At noon on Saturday, Lucifer (M530B) was on the Juniper Loop and walked into the woods by the NW shed.  By 1530, he was between the Lodge and the creek, in the general area of females (total of 14).  He remained in that general area until he crossed over to the Juniper Loop on Sunday morning (by 9 am).  No food was delivered while I was watching on Sunday.  He drank from the rain water in the pellet troughs and he grazed with other species (mostly sable) on the pasture east of Juniper Loop.  No females appeared on Juniper Loop.

Lucifer checked out a few females very briefly and did not persist  in following them.  He briefly escalated with an addax, who de-escalated.  He watched addax.  He was not following the female that gave birth on 7/28.  She was still bagged up.

Although M664O was with the rest of the group prior to the rainstorm, he was with the male calf and a female SW of the Lodge Road (by the Creek) Saturday evening and Sunday morning.  I saw no interactions between Lucifer and the young males (M664O is a yearling with horns about 6-10 inches, and M91′F61 was born in 4/09 so is about 3-4 months with horn buds 2-3 inches).
