Would anyone, by chance, happen to know on which (actual) base Reichenbach's Aufzählung der Colibris may be told to have been published in "March" 1854 ?

In the proposal, Bruce & Stiles suggest that this was "demonstrated" (= claimed ?) by Cabanis & Heine 1860, but Cabanis & Heine "Mai" = May (not "März" = March). This would make this work later than the separate edition of Bonaparte's Tableau des oiseaux-mouches (presented to the Académie and said to be just published at the séance of 24 April 1854: see here; noticed as having been published on 6 May 1854 in Bibliogr. France: here; "Jun." = June as per C&H 1860 presumably refers to the journal version of the work, which appeared later).

(In the contemporary literature, I can find no references to it as a published work before the second half of 1854 -- see here. The earliest actual date on which I find a reference to the Extraheft (only the Erinnerungsschrift cited, not the Aufzählung; I'm not fully sure this would concern it too) is 21 Sep 1854 -- here.)
Bonaparte did not use any name from Reichenbach's Aufzählung in Tableau des oiseaux-mouches, but he used a significant number of them in :
  • Bonaparte CL. 1854. Conspectus systematis ornithologiae. Ann. Sci. Nat. (Zool.), sér. 4, 1: 105-152.
...of which:
The Trochilidae were on pp. 135-138 of the journal version (32-34 of the separate), thus would have been in any case demonstrably published with the separate edition of the work on 29 May 1854.

The Aufzählung must then have been published before this date, and would presumably have reached Bonaparte between his writing of Tableau des oiseaux-mouches (before 24 Apr 1854, see above), and his writing of Conspectus systematis ornithologiae, thus quite likely in late Apr or early May.

This may be more consistent with the date of publication originally claimed by Cabanis & Heine in 1860 (May, presumably reflecting the testimony of Cabanis, who had been the editor of the volume that contained the work), than with the 'corrected' date claimed by Heine in 1863 (March, offered without explanations by an author who was too young to have seen the publication of this volume; possibly resulting of the misinterpretation, as a date of publication, of a date appearing in the volume which was not one). It's probably not enough to be really sure, though.

Phylogeography and morphometric variation in the Cinnamon Hummingbird complex: Amazilia rutila (Aves: Trochilidae) - Avian Research

The Mesoamerican dominion is a biogeographic area of great interest due to its complex topography and distinctive climatic history. This area has a large diversity of habitats, including tropical deciduous forests, which house a large number of endemic species. Here, we assess phylogeographic pattern, genetic and morphometric variation in the Cinnamon Hummingbird complex Amazilia rutila, which prefers habitats in this region. This resident species is distributed along the Pacific coast from Sinaloa—including the Tres Marías Islands in Mexico to Costa Rica, and from the coastal plain of the Yucatán Peninsula of Mexico south to Belize.
We obtained genetic data from 85 samples of A. rutila, using 4 different molecular markers (mtDNA: ND2, COI; nDNA: ODC, MUSK) on which we performed analyses of population structure (median-joining network, STRUCTURE, FST, AMOVA), Bayesian and Maximum Likelihood phylogenetic analyses, and divergence time estimates. In order to evaluate the historic suitability of environmental conditions, we constructed projection models using past scenarios (Pleistocene periods), and conducted Bayesian Skyline Plots (BSP) to visualize changes in population sizes over time. To analyze morphometric variation, we took measurements of 5 morphological traits from 210 study skins. We tested for differences between sexes, differences among geographic groups (defined based on genetic results), and used PCA to examine the variation in multivariate space.
Using mtDNA, we recovered four main geographic groups: the Pacific coast, the Tres Marías Islands, the Chiapas region, and the Yucatán Peninsula together with Central America. These same groups were recovered by the phylogenetic results based on the multilocus dataset. Demography based on BSP results showed constant population size over time throughout the A. rutila complex and within each geographic group. Ecological niche model projections onto past scenarios revealed no drastic changes in suitable conditions, but revealed some possible refuges. Morphometric results showed minor sexual dimorphism in this species and statistically significant differences between geographic groups. The Tres Marías Islands population was the most differentiated, having larger body size than the remaining groups.
The best supported evolutionary hypothesis of diversification within this group corresponds to geographic isolation (limited gene flow), differences in current environmental conditions, and historical habitat fragmentation promoted by past events (Pleistocene refugia). Four well-defined clades comprise the A. rutila complex, and we assess the importance of a taxonomic reevaluation. Our data suggest that both of A. r. graysoni (Tres Marías Islands) and A. r. rutila (Pacific coast) should be considered full species. The other two strongly supported clades are: (a) the Chiapas group (southern Mexico), and (b) the populations from Yucatán Peninsula and Central America. These clades belong to the corallirostris taxon, which needs to be split and properly named.
