Steve Hager and the Augustana Darwin Club led a birding tour of the campus on 18 September. The club witnessed a great turnout that included students, faculty, and staff.
We ended up seeing a total of 19 species during our walk despite many bird calls/songs being drowned out by the water fountains in the slough and construction in the quad. We got off to a great start when Sharon Varallo spotted a Green Heron feeding at the edge of the slough. Dave Dehnel located a Nashville Warbler gleaning insects high in an oak tree. Our only Ovenbird (a large warbler named for its domed, oven-looking nest constructed on the floor of mature forests) was documented by Anne Earel. Another highlight was the sighting of an adult male American Redstart, shown below.

We report clinical, cytogenetic, and comparative genomic hybridization findings for three siblings with an unbalanced 4q;16q translocation, minor malformations, and cognitive abnormalities, including childhood apraxia of speech, a rare, severe motor speech disorder. Breakpoint findings indicate that in addition to possible contributions from duplicated genes on chromosome 16, haploinsufficiency of one or more of 11 genes deleted in the telomeric region of the long arm of chromosome 4 is the likely cause of the speech disorder, the associated impairments in cognition and language, and the dysmorphic features. The present findings are the first to document childhood apraxia of speech in a multiplex family using contemporary speech measures. We suggest that genotype-phenotype studies of childhood apraxia of speech occurring in complex neurodevelopmental disorders can elucidate the pathophysiology of this disorder.
