1000th observation passed!

Today, the AfriBats-project passed its 1000th observation with a beautiful series of long-term observations of a family of Mauritian tomb bats (Taphozous mauritianus) by Martin Grimm from Tanzania.

Since the last collection of highlights, there's been a fantastic and increasing number of bat observations from around Africa, Madagascar and smaller islands. Some were obtained during dedicated research projects while a large number was contributed by interested citizen scientists.

Jack Bradbury, of Hypsignathus-fame, shared some of his historic bat observations from Gabon, which date back to the 1970ies and which were taken during a time when technology was far less advanced than today. Hard to imagine the serious constraints to bat research ...more ↓

Description

Part of the BCEAO-Niamey colony of Straw-Colored Fruit Bats (not identifiable in the attached photos, in which they are the dark blotches in the foliage of the ca. 6m-to-8m-tall trees inside the northern compound perimeter wall of the BCEAO office, located between Petit Marchais & the traffic circle connecting to Rue General DeGaulle) in central Niamey. These photos were taken between 17:48 & 17:52 pm on Thursday evening 6th November, while I was easing through heavy traffic (traveling from east-south-east to wast-north-west) on the way home from my office via Petit Marchais. Note how close the vehicles are to the bats' roosting site -- which consists of a ca. 150m-long J-shaped string of about 23 trees along the inside of the northern compound wall, continuing for another 12-15 trees going around the northwest corner & western boundaries of the bank compound north of the main entrance on the west side of the compound. Perhaps because of the 3m-high wall & armed security guards patrolling inside of the compound perimeter wall, the bats are relatively undisturbed in this mid-city chaos despite being almost low enough to touch.
I conducted a census of this colony several days later, at mid-day on 9th November (reported as a separate observation, no. 1064391) & estimated the population of this colony at 3400 individuals, with individual trees having from one individual bat (2 trees) to at least 250 individuals (also 2 trees). As the colony is in a curvilinear group of short trees, & is just one-tree wide by at most 200m long, observations on this colony are relatively easy to make so long as one does nothing to attract unwanted attention of the bank's security staff, or those of the national Treasury office located across the street.

Description

Largest colony of the largest resident fruit bat species in Niamey, Niger. Conservatively estimated population present in thus colony between 11:00 a.m. & 12:00 noon on Sunday 09 Nov 2014, in 34 short roost trees along the inside of the northern & northwestern compund perimeter walls of the Regional Bank Office for Niger, was circa 3400 individuals, with individual roost trees having from a single bat (2 trees) to two-hundred & fifty individual bats (also 2 trees) roosting during the 15 minutes it took me to perform this census (which is supposed to take place monthly, but was last completed in March).

Additional details, including geographical coordinates of this observation [& reference to some photos of the same colony taken this past Thursday evening (6th November 2014) while I was stuck in traffic on the adjacent street coming from 'Petit Marchais'], have now been added -- with the 6th November sightings now added as a separate observation (no. 1092981).

Lieber Jakob,
hier kommt wie versprochen Baby Casper :)

05/10/-27/10/: the two were here every day.

When I returned from leave they were still here.

07/11/-10/11/: the two were here every day.

11/11/: no sign of them, but we had bad weather the night before (I think they found shelter somewhere else, because the following day they were back again)

12/11/-16/11: the two were here every day.

17/11/-18/11/: no sign of them (again bad weather...)

19/11/-22/11/: the two were here every day.

The Baby is growing nicely & I will still follow up on them!

Cheers Anna

About

The bat fauna of Africa and surrounding islands boasts nearly 300 species, but the distributions of many species are poorly known. Despite the crucial role of bats (Chiroptera) as pollinators and seed dispersers of plants as well as predators of insects, one-fifth of the bat species in Africa are threatened, and populations are declining due to habitat loss, disturbance and destruction of roost ...more ↓
