2006 Field Season
Erin Gott— 10 March 2006 — in Aplomado Falcon Restoration ShareWe’ve accomplished a lot since the last update, so here is a quick summary to get everyone up to
The 2005 hack season saw record breaking numbers with 84% of 138 released Aplomado Falcons, from six sites, reaching independence. A total of 1,142 captive-bred Aplomado Falcons have now been released in Texas.

Paul and I returned to South Texas on 1 February. After setting up shop at Laguna Atascosa NWR, Paul and I sat down to design a new barred nest box. Although our older nest boxes work well in most circumstances, there are a few falcon territories on LANWR that continually fail to fledge young. One such territory has failed to fledge a single falcon after eight years of adult occupancy. Each year since 1997 an adult pair of Aplomado Falcons produced eggs/ young chicks only to mysteriously fail. In 2005 the pair started incubating chicks in a barred structure and appeared to have young before the nest failed. Based on the evidence (or lack of) found at the nest site, Paul and I believe the culprit to be avian. The new barred structure is longer, wider and lower with narrower bar spacings. Hopefully this new barred nest box will allow the falcons to access the nest while preventing unwanted predators. Paul and I built four of these new barred nest boxes, we placed three on LANWR and the fourth on a MINWR neighboring territory. Four older barred nest boxes were also placed in similar territories.
To date, only five territorial Aplomado Falcon pairs have been observed in South Texas. Only
all of us in the field.
